# Manufacture of configured composite unpowered gliders

## 1. Scope and Applicability

Manufacturing foreground of a new complete configured non-inflatable unpowered rigid-wing sailplane with locally moulded glass/carbon-epoxy airframe and bonded sandwich construction. The selected route is approved wet layup with controlled curing and actual declared core/structural reinforcement, not a universal production recipe. Existing woven-glass fabric, electrical wiring and aircraft-engine material/component PCRs cover upstream products, not this propulsion-free complete aircraft integration. No complete material glider PCR was identified in the manifest scan. Balloons/dirigibles, hang gliders, inflatable craft, powered or motor-assisted sailplanes, kit/incomplete airframes, separately supplied parts, all-metal/wood/prepreg routes, repair and refurbishment are excluded. Exclude customer flight, aerotow/winch services during use, glide performance, passenger transport, airfield infrastructure, lifetime and disposal. Performed manufacturing acceptance trials remain inside their measured factory boundary. Historical LS8 configuration/weighing evidence and a separate manufacturer’s carbon production example do not establish one combined model recipe or current factory quantities. Candidate authored methodology awaits independent scientific review.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_mass` | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | M = accepted net mass of one complete unit of the same configuration in kg; collect using cp_mass. |
| `electric_energy` | electricity rows | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | MJ | Meter actual supplied stage energy;1kWh=3.6MJ. Keep measured energy and actual attribution records; normalize per-unit MJ by M. |

## 5. System Boundary

The foreground begins with actual resin, dry reinforcement/core and independently scoped purchased equipment at plant and ends at complete configured manufacturing acceptance. Include actual mould preparation, measured layup/cure/temperature control, structural bonding, cured trimming/drilling/inspection, conditional finishing, outfitting, rework and performed acceptance work. Vacuum consolidation, oven post-cure, machining coolant, release agent, acetone cleaning and gelcoat are included only when actual controlled route records show them; no autoclave, solvent emission or cure condition is universally mandatory. Expand actual vacuum film, peel ply, breather, abrasives, filters, catalyst, radio/battery/wiring, lubrication, trim ballast, ballast plumbing, packaging, transport and other missing specific exchanges from the full BOM/route before claiming complete foreground coverage. Purchased complete airframe shells would change this local moulding boundary and cannot be counted with their duplicated resin/fibre/cure. Link upstream production and receiving treatment only through matched independent datasets; this document does not establish complete cradle-to-gate coverage. Operational flights, customer tow/winch and maintenance remain outside.

### Boundary Abstraction

| recursive_input_rule | Count a supplied assembly once, including its stated internals; expand local fabrication separately |
| upstream_dataset_requirement | Match material chemistry/form/precursor, equipment design/completeness, actual provider geography/voltage and waste receiver route |
| disclosure | Manufacturing foreground with explicit unresolved identities, current BOM/weight/route observations and missing links |
| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `boundary_supplied` | assemblies | Reconcile supply inclusion, independently measured installed component kg and net complete-aircraft M; subtract nothing without measured state corrections. Included fluid/finish/hardware is not a duplicate separate receipt. |  |
| `boundary_acceptance` | factory tests | Include actual control/release/gear checks and performed trial/rework. If an actual manufacturing flight acceptance uses a tug or winch, add separately identified measured supplied test service and actual energy/receiver exchanges; do not assign towing fuel to the unpowered glider or infer operating-life flights. Test payload and water are not retained net M. |  |

###### Unmixed DGEBA epoxy base resin (`epoxy_base`)

Only if the current approved wet-lamination formulation actually uses supplied DGEBA base resin matching this identity. Record supplier certificate, reactive diluents and actual retained formulation; a filled or blended resin outside this identity needs its own unresolved card. Weigh net issues/returns before separately counted hardener. Historical repair resin trade names establish neither DGEBA purity nor a new-production recipe.

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `allocation_direct` | shared tooling/production | Separate actual aircraft order/configuration and meter identifiable mould/cure/trim/finish/test work first. For shared cure batches use recorded thermal cycle, occupancy and metered demand with demonstrated causal allocation; aircraft count or kg is not universally causal. Preserve total energy/stock, actual rejected trials/rework and accepted denominator, with sensitivity and intermediate records. |  |
| `allocation_recovery` | waste and reuse | Record internal dry-stock reuse and solvent recovery separately from actual exports. Use subdivision or demonstrated causal allocation for a real co-product; disclose alternatives and sensitivity if unavailable. No automatic recycling yield, avoided virgin fibre/resin credit or price-based rule. Capture and emission are separate mass destinations. |  |

## 8. Foreground Data Collection, Calculation, and Quality Rules

### Data Collection Protocols

| protocol_id | process_id | flow_role | record_type | raw_fields | collection_method | unit | frequency | temporal_coverage | site_scope | aggregation_rule | quality_evidence |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| `cp_mass` | acceptance | reference product | controlled complete-unit acceptance weight | configuration; accepted net mass M; aircraft serial; original component/support weights; calibration/tare; dry tanks; installed equipment; independently measured state corrections and mass balance | Use controlled acceptance records for the accepted complete unit of the same configuration. | kg | each accepted aircraft/configuration change | declared representative current production period | named actual manufacturing site | accepted net mass per unit | original actual calibrated empty-state weighings and independent component balance |
| `cp_stock` | all processes | single chemical/material stock | stock issue and batch record | single material/SDS/lot/formulation; issues; returns; retained amount; rejects/rework; mix/cure/ply record; accepted count | Weigh net actual stock issues/returns and match each approved ply/mix/joint/finish batch; retain supplied chemistry and inclusion. Record measured consumption, cured retention and residues separately. No catalogue resin/fibre fraction or repair mix-ratio proxy. | kg | each lot and reporting period | declared representative current production period | named actual manufacturing site | actual attributable stock kg / accepted units of the same configuration | scale/tare, supplier/SDS, signed batch/ply/cure records and balances |
| `cp_parts` | outfit | single supplied component | receipt installed-weight and configuration record | one component/drawing/material/serial/count; supplied net kg; installed kg; included hardware/charges; returns; accepted count | Measure actual installed supplied component kg, keeping count/serial for traceability. Reconcile complete modules and split gear/wheel receipts, avoiding included fastener/fluid duplication. Independent component mass checks complete M. | kg | each design/lot and aircraft | declared representative current production period | named actual manufacturing site | actual installed supplied kg / accepted units of the same configuration | calibrated receipt/installed weight, drawings and inclusion/serial reconciliation |
| `cp_energy` | all processes | single electricity interface | meter and stage attribution | meter/site/provider/voltage; gross energy kWh; period/batch/cycle/idle/rework; actual accepted count; causal attribution | Read calibrated electricity meters at the actual supply/stage interface; retain stage/batch duration and actual sharing evidence. Convert kWh to MJ using1kWh=3.6MJ, preserving imports and explicit supplier gate. | MJ | each batch/period and route change | declared representative current production period | named actual manufacturing site | actual attributed stage MJ / accepted units of the same configuration | meter calibration, invoices/cycles and causal balance |
| `cp_waste` | all processes | single physical waste stream | segregated receiver shipment | one waste chemistry/cure/contamination; net kg/tare; source process; reuse/recovery; receiver route; accepted count | Weigh each separately identified actual exported stream excluding container and retain receiver tickets and state analysis. Do not merge GFRP/CFRP, cured/uncured material, spent solvent and captured dust. | kg | each shipment and period | declared representative current production period | named actual manufacturing site | actual exported net waste kg / accepted units of the same configuration | scale/tare, analytical and receiver/source balance |
| `cp_emission` | join | single residual atmospheric substance | sampled air release | substance/CAS/particle fraction; air submedium; post-control sample concentration/flow/time; limits/uncertainty; actual accepted count | Quantify actual post-control particulate or separately acetone mass with compound/medium-specific measurements; for acetone a documented closed solvent balance may support quantity if recovery/residue/retention are resolved. Retain uncertainty and distinguish absent, not measured and below detection; none is automatic zero. | kg | representative actual route/control period | declared representative current production period | named actual manufacturing site | actual released kg / accepted units of the same configuration | sampling/lab calibration, operating duration and substance balance |
| `cp_configuration` | all processes | complete glider configuration | controlled as-built acceptance | model/serial; full wing/winglet/tail configuration; complete BOM/route revision; equipment/ballast tanks; make-or-buy; actual tests; delivery state | Trace current approved as-built BOM, layup/cure/bond procedures, deviations and performed tests. Qualify complete delivered equipment and net empty state; retain independently measured state corrections rather than source catalogue weights. | kg | each aircraft/configuration and route change | declared representative current production period | named actual manufacturing site | qualifiers accompany each same-configuration accepted unit | signed drawing/BOM/procedure/inspection and physical-state records |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| `normalize_mass` | all inventory rows | q_ref = q_item / M; q_item = exchange amount per one accepted finished unit; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |  |
| `period_conversion` | order records | For one actual same configuration, attribute measured period totals to accepted aircraft through documented causal records and compute q_item from attributed exchange / accepted aircraft. Keep raw totals, rejects/rework, accepted count and intermediate values. Do not pool different wing/equipment configurations without an explicit physical model. | cp_stock; cp_parts; cp_energy; cp_mass | q_item |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `mass_provenance` | cp_mass | Controlled acceptance M must originate in current actual calibrated empty-aircraft weighing for the same complete serial/configuration, preserving original readings, component/support identification, level/support conditions, calibration, zero, auxiliary support tare and uncertainty. The actual method may sum separately weighed distinct complete parts or use a demonstrated complete supported-aircraft weighing method; reconcile the same complete installed configuration and all independent component masses. No fictional whole-aircraft platform scale is prescribed. A measured support reaction reported as force requires the actual metrological force-to-mass basis, not an assumed universal gravity constant. The retained LS8 manual p.2-1 is historical physical-method evidence, not current model records or a universal new-aircraft acceptance protocol. Without actual originals and closure retain the measurement/scientific gap; do not claim observed physically complete data. | dg-ls8-historical; cp_mass; cp_parts; cp_configuration |
| `net_empty_configuration` | accepted glider | M includes the accepted declared complete wings/winglets/tail, structural airframe, permanently installed controls/gear/canopy/seat/harness/instruments and actually delivered permanent non-propulsion equipment and retained working charges once. Declare original as-weighed state and separately measured signed corrections. Exclude pilot, removable service payload/parachute unless explicitly part of the permanent delivered configuration, water ballast, temporary balancing/test loads, supports, lifting equipment and packaging. Dry ballast tank hardware remains. Installed trim weights or cockpit battery must be individually identified and weighed if included. Do not use maximum takeoff mass, catalog empty mass, legal limits, a guessed resin fraction or ballast-filled weight as M. | cp_mass; cp_parts; cp_configuration |
| `route_and_balance` | all exchanges | The current approved full BOM, ply/core architecture, actual supplied chemistry and production travellers determine exact quantities and conditions. Check resin/hardener and adhesive mixture inclusion, reaction/retention and GFRP/CFRP stock-to-product-to-waste balances. Capture is not air emission. Add all actual missing specific equipment, vacuum consumables, charge, cleaning, packaging, test-service, transport and receiver exchanges before completeness claims; validate current acceptance criteria, rework, limits, uncertainty and supply links. No universal yield, resin ratio, cure cycle, core density, equipment weight or service life is set. | cp_stock; cp_parts; cp_energy; cp_waste; cp_emission; cp_configuration |
| `source_limits` | external evidence | LS8 retained manual (December2009 baseline, later amendments through June2016) supplies historical system/physical-weighing context only. Its repair resin/fabric/core and finishing lists are not a new-production BOM, cure recipe, density conversion, current legal approval or lifetime mandate. Schempp-Hirth October2018 MINIMOA pp.04/07 supplies a separate historical carbon spar/production example, without proving this glider’s exact formulation, core chemistry or process conditions. Current plant qualification, weighing originals and complete configuration remain independent scientific-review requirements. | dg-ls8-historical; schempp-minimoa-2018 |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `validation_reference` | reference_flow | Verify complete unpowered rigid-wing configuration, positive physically generated M kg and independent mass_provenance/net_empty_configuration. Reference product must equal finished_glider selected flow; a broader product UUID does not establish exact configuration or model weight. |  |
| `validation_route` | all processes | Check actual wet layup/core/cure/bond/finish qualification and performed trimming/outfit/tests, with stage meter and stock/rework/waste balances. No repair prescription substituted for current new-production evidence; purchased modules and internal stocks must not duplicate. |  |
| `validation_identity` | all flow rows | Verify actual type/substance, reference property and unit group, state/concentration/precursor, supply gate and official bilingual name. Bare glass fibre is not woven fabric; wafer-production acetone is not automatically cleaning supply; non-cellular plastic is not PVC foam; generic release agent is not demonstrated PVA solution. Indoor/soil/upper-air acetone is not immediate unspecified outdoor air. Keep unmatched rows unresolved by exact row_id; do not change public properties. |  |
| `validation_claims` | claims | Mechanical PCR pass is not scientific approval, current aircraft legal/type approval, actual plant inventory completeness, mass observation or flight-function equivalence. Require current full manufacturing/weighing/supplier records and matched links for any broader dataset claim. |  |

## 10. Published Dataset Profile

| Field | Value |

| dataset_role | Configured wet-layup composite unpowered glider manufacturing foreground; heading does not assert publication |
| downstream_use | secondary_dataset; background_dataset |

| excluded_use | Flight-hour/glide performance, powered craft, other airframe routes, loose parts/use/tow/repair/lifetime/disposal and approval |

| required_quality_disclosure | Remaining identity/BOM/route/weight/link gaps, historical evidence applicability, uncertainty/limits, actual trials/rework/recovery/exports and allocation sensitivity |
| update_trigger | Wing/airframe material/layup/core/cure/bond/finish, permanent equipment/make-or-buy, actual empty measurement/delivery state, plant/period/test or provider-interface change |
