Thrust reversal
Thrust reversal, also called reverse thrust, is an operating mode for jet engines equipped with a thrust reverser when thrust is directed forwards for slowing an aircraft after landing. It assists wheel braking and reduces brake wear. Fatal accidents have been caused by inadvertent use of thrust reversal in flight.
Aircraft propellers also have an operating mode for directing their thrust forwards for braking, known as operating in reverse pitch.
The main requirement for thrust reversal is to supplement wheel brakes when stopping on a runway. Aside from this, aircraft with thrust reversers have used them to give extra drag in flight to enable steeper descents. On the ground some aircraft types are allowed to make minor positioning moves backwards.
A thrust reverser works by changing the direction of the exhaust as it leaves a jet engine so instead of coming straight out of the back it is interrupted as it leaves and turned partially forwards. Alternatively its path inside the engine is blocked and it comes out of the sides, being turned partially forwards at the same time.
The engine is now acting against the aircraft motion as a braking device and needs to run at high speed, as during take-off, to give the required amount of reverse thrust.
To be most effective at slowing the aircraft reverse thrust is used while the aircraft is still at high speed as soon as it has landed on the runway. As the aircraft slows down the thrust reverse is cancelled because the exhaust, which is moving forwards, will be sucked back into the engine at slower speeds. Wheel braking takes over.
Reverse thrust is used on most civil jet aircraft, airliners and business jets. One exception is the BAe 146 which has a fuselage tip-mounted air brake instead. It is also not always required for all engines on a particular aircraft type if it has more than 2 engines. The 4-engined Airbus A380 only needs reversers on 2 engines and the 3-engined Dassault Falcon aircraft only needs a reverser on the center engine.
Reverse thrust has been used on combat aircraft, such as the Tornado and Viggen.
