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 ...
Axi-symmetric stall, more commonly known as compressor surge; or pressure surge, is a complete breakdown in compression resulting in a reversal of flow and the violent expulsion of previously compressed air out through the engine intake, due to the compressor's inability to continue working against the already-compressed air behind it.
The tests require engine manufacturers to carry out at least two tests of the engine, to make sure that the engine can survive a compressor or fan blade breaking off within the engine and a turbine blade breaking off within the engine, without fragments being thrown through the outside enclosure of the engine, creating a contained engine failure.
A flawed part or design failing may have caused the engine on board a Qantas Airways (QUBSF) Airbus A380 to explode in mid-air, Qantas CEO Alan Joyce said. The explosion on a Thursday flight from ...
The tendency of powerful propeller aircraft to roll in reaction to engine torque creates a risk of accelerated stalls. When an aircraft such as a Mitsubishi MU-2 is flying close to its stall speed, the sudden application of full power may cause it to roll, creating the same aerodynamic conditions that induce an accelerated stall in turning ...
P-Factor therefore determines which engine is critical engine. [6] For most aircraft (which have clockwise rotating propellers), the left engine is the critical engine. For aircraft with counter-rotating propellers (i.e. not rotating in the same direction) the P-factor moments are equal and both engines are considered equally critical. Fig. 1.
The engine had been replaced with a spare engine, lent by Rolls-Royce, from an older model which did not include a hydraulic pump. Despite the lead mechanic's concerns, Air Transat authorized the use of a part from a similar engine, an adaptation that did not maintain adequate clearance between the hydraulic lines and the fuel line.
Uncontained engine failures occur when parts within an aircraft's engine separate and break free. Pages in category "Airliner accidents and incidents involving uncontained engine failure" The following 29 pages are in this category, out of 29 total.
