Some aircraft use lift spoilers on landing approach to control descent without changing the aircraft's attitude. One jet airliner not fitted with lift spoilers was the Douglas DC-8 which used reverse thrust in flight on the two inboard engines to control descent speed (however the aircraft was fitted with lift dumpers).
The B-52G has no ailerons. The spoilers, situated inboard and forward of the trailing edge, are used for lateral control at high speeds to prevent excessive wing twist. [4] The Mitsubishi Diamond Jet, Beechjet, and Hawker 400 family of business aircraft incorporate full length spoilerons that also double as speed spoilers during flight and landing.
Most fixed-wing aircraft have a trimming control surface on the elevator, but larger aircraft also have a trim control for the rudder, and another for the ailerons. The rudder trim is to counter any asymmetric thrust from the engines. Aileron trim is to counter the effects of the centre of gravity being displaced from the aircraft centerline ...
The FAA publicly identified an “unsafe condition” that could result in a “loss of control” of certain Boeing 737 Max jets because of “nonconforming” installation of spoiler control wires.
Virtually all jet-powered aircraft have an air brake or, in the case of most airliners, lift spoilers that also act as air brakes. Propeller-driven aircraft benefit from the natural braking effect of the propeller when engine power is reduced to idle, but jet engines have no similar braking effect, so jet-powered aircraft must use air brakes to ...
A single cylinder head temperature (CHT) sensor, or in more sophisticated installations, an array of sensors, one for each cylinder, may be employed to monitor the temperature and cooling rate of the engine. Spoilers on the wings may also be deployed to lose lift without having to reduce engine power substantially, slowing the rate of engine ...
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing ...
The Skyhawk has a short-span delta wing configuration, a tricycle undercarriage, and is powered by a single turbojet engine. The U.S. Navy issued a contract for the aircraft on 12 June 1952. On 22 June 1954, the XA4D-1 prototype performed its maiden flight; it went on to set a world speed record of 695.163 mph on 15 October 1955. [1]
