Propulsion system (aircraft)
As a drive system (engl. Propulsion system ) is for a civil aircraft, one of the engine , engine cowling and thrust reversers existing assembly designated.
Demarcation
In civil aircraft, the engines are usually arranged outside the airframe of the aircraft. As a result, the aircraft manufacturer can relatively easily specify system limits and performance parameters ; this also enables the development and manufacture of the entire assembly to be outsourced in a comparatively simple manner. In addition to thrust , such a drive system also provides electrical and hydraulic energy, for example .
A distinction must be made between the term aviation propulsion as a collective term compared to the engines used to propel aircraft.
System limits
The system of the US Air Transport Association is mostly used to delimit the systems of a civil aircraft . Their ATA Chapter (. English ATA Chapter ) adjoin the main group drive follows (cf. ATA Chapter 70 ff..)
- Engine including attachments such as the engine-side fuel pumps and the electric generator
- Thrust reverser unit
- The aerodynamic fairing of the engine including the air inlet and covers ( cowlings ) without a load-bearing function. Here there are problems of definition for engine nacelle (engl. Nacelle ) comprising a structural part is.
The engine strut (English pylon , see ATA Chapter 54) is a structural part of the aircraft. The aircraft-side fuel system , which includes the pumps and lines with which fuel is pumped from tank to tank and ultimately to the engine to trim the aircraft , is also not part of the propulsion system (see ATA chapter 28).
