The Dassault Falcon 5X is a business jet that was under development by Dassault Aviation. Unfortunately, the Falcon 5X program was terminated by Dassault Aviation due to various technical issues. Generally, the thermal efficiency of an aircraft is not directly calculated or specified for an entire aircraft like it is for an engine. Instead, thermal efficiency is often discussed in the context of the propulsion system or engines powering the aircraft.
However, The thermal efficiency is expressed mathematically as:
where:
- is the thermal efficiency,
- is the thrust produced by the engine,
- is the jet velocity,
- ṁf is the mass flow rate of fuel,
- is the specific enthalpy of the fuel.
