Commercial Aircraft engine concept design
- How do the Manufacturers (OEMs) plan for a Commercial Aircraft
engine concept design? What Challenges & factors shape the final product ?
- First thing Airframers like 'Airbus' & 'Boeing' do to
their 'aircraft design plan' is to involve a 'Propulsion system maker' like GE,
Rolls-Royce, P&W, or others.
- Sometimes this chemistry between Airframer & Engine maker does not work.
- Last week, we witnessed Rolls-Royce freezing it's ambitious
‘UltraFan’ Project despite deep financial backup, much hype & cutting edge the technology involved to it.
The Factors that really affect a commercial aircraft engine
concept design is:
Business Case Of Engine.
- Development Cost.
- Manufacturing cost.
The revenue source for Engine.
- Engine Unit sale.
- Sales Volume/Market demand.
- Spare parts/Supply chain.
Aircraft specific Requirement.
- Passengers capacity.
- Cruise speed & Insertion altitude.
- Balanced field length.
- Power & bleed air-off takes (usage).
Customer Interest value.
- Revenue Generation.
- Payload Offer.
- Range definition.
Cost of Ownership.
- Price of the engine.
- Fuel Burn (efficiency).
- Maintenance cost.
Regulatory Requirement.
