Civil and Military Certification of Propulsion Systems To Support Aircraft and Helicopter Operations
Instructors: Luc Deniger, Derek FergusonPrintable Course Information (PDF)
This course provides fundamental design considerations for certification of propulsion systems. It discusses design requirements, methods of compliance, tests and analyses to demonstrate compliance to civil and military certification requirements. Using practical examples, the participants will gain knowledge to support their role as propulsion engineers.
Includes instruction, course materials, refreshments and lunches. The course notes are for participants only and are not for sale.

Introduction and review of propulsion systems fundamentals:
- Classification, design requirements and objectives of propulsion systems
- Certification regulations and design rules (FAR 33, 23, 25, 27, 29, 35; EASA CS-E, 25, 29; CS-VLA, CS-P; DEF-STAN 00-971; MIL-HDBK-516B), general goals in propulsion system design
- Helicopter and aircraft propulsion systems` installation considerations
General certification aspects: certification basis; certification plan; methods of demonstrating compliance.
Engine certification (gas turbine engines):
- Basic design and construction;
- Failure analysis;
- Engine controls, including FADEC;
- Induction system icing;
- Bird ingestion;
- Certification tests: endurance; vibration; operation; over temperature; over speed; rotor locking test; blade containment and rotor unbalance tests; engine-propeller systems tests; etcetera.
Engine certification (continued):
- Transmissions (turbo-shafts, turboprops)
- Critical component lives
- Instructions for continuing airworthiness.
- Basic design and construction
- Tests and inspections
- Failure analysis (electronic controls).
Aircraft and Helicopter propulsion systems installation considerations:
- General aspects
- Propulsion system vibration
- Fuel system: Design and certification tests, independence, unusable fuel supply, hot weather operation, cold weather operation, fuel tanks, pumps, filters or strainers, vents, drains, pressure refueling and fueling provisions, fuel jettisoning
- Flammable fluids considerations and engineering survey/inspection
- Oil system: tanks, lines and fittings, strainer or filter, drains, radiators, valves
- Powerplant cooling tests
- Induction system: air induction, induction system icing protection, induction system screens
- Environmental aspects (rain, ice/hail, snow, sand, volcanic ash, etcetera.)
Aircraft and Helicopter propulsion systems installation considerations (continued):
- Exhaust system
- Powerplant controls
- Auxiliary power unit
- Powerplant fire protection: fire zones, fire extinguishing systems, fire detection systems
- Thrust reversers (aircraft)
- Rotor brake (helicopter)
- Rotor drive system (helicopters): design and rotor drive system and control mechanism tests.
- Continuing Airworthiness aspects: in-service safety issues and risk management
- Airworthiness Directives; corrective action directives such as SFAR 88
- Support to operations: performance and installed thrust; ETOPS/EROPS (aircraft); Category A or B operations (helicopters); One Engine Inoperative (helicopters); Heli-Logging; SAR Operations (aircraft and helicopters); single engine IFR aircraft
