Aircraft engine performance refers to factors including thrust or shaft power for fuel consumed, weight, cost, outside dimensions and life. It includes meeting regulated environmental limits which apply to emissions of noise and chemical pollutants, and regulated safety aspects which require a design that can safely tolerate environmental hazards such as birds, rain, hail and icing conditions.
Aircraft performance refers to the ability of airplanes and helicopters to accomplish certain useful things. [1] It is an important consideration when designing and testing aircraft, to ensure the aircraft can be operated in an efficient and economic manner. [ 2 ]
The performance data for landing an aircraft can be obtained from the aircraft's flight manual or pilot's operating handbook. It will state the distance required to bring the aircraft to a stop under ideal conditions, assuming the aircraft crosses the runway threshold at a height of 50 ft, at the correct speed.
Factors affecting the balanced field length include: the mass of the aircraft – higher mass results in slower acceleration and higher takeoff speed; engine thrust – affected by temperature and air pressure, but reduced thrust can also be deliberately selected by the pilot
Aircraft taking off from a “hot and high” airport, such as the Quito Airport or Mexico City, are at a significant aerodynamic disadvantage. The following effects result from a density altitude that is higher than the actual physical altitude: [2] An aircraft will accelerate more slowly on takeoff as a result of its reduced power production.
The type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.
The critical engine of a multi-engine fixed-wing aircraft is the engine that, in the event of failure, would most adversely affect the performance or handling abilities of an aircraft. On propeller aircraft, there is a difference in the remaining yawing moments after failure of the left or the right (outboard) engine when all propellers rotate ...
This includes the human-machine interface. The way in which particular vehicle factors affect flying qualities has been studied in aircraft for decades, [3] and reference standards for the flying qualities of both fixed-wing aircraft [4] and rotary-wing aircraft [5] have been developed and are now in common use. These standards define a subset ...
