On aircraft using jet engines, thrust reversal is accomplished by causing the jet blast to flow forward. The engine does not run or rotate in reverse; instead, thrust reversing devices are used to block the blast and redirect it forward.
In most cases, you want to apply reverse thrust as soon as the wheels are on the ground. Some aircraft can use in-flight thrust reversal for a quick reduction of speed or altitude, but these tend to be military aircraft that need the improved performance.
Normally, a jet engine has one of two types of thrust reversers: a target reverser or a cascade reverser. Target reversers are simple clamshell doors that swivel from the stowed position at the engine tailpipe to block all of the outflow and redirect some component of the thrust forward.
22 Νοε 2017 · A thrust reverser, which allows for more rapid deceleration during landing, is a critical component of many jet aircraft. By acting against the aircraft’s forward travel, a thrust reverser system helps the jet slow down just after touchdown. This reduces wear on brakes and facilitates shortened landing distances.
4 Σεπ 2023 · Thrust reversers enhance an aircraft’s braking efficiency, particularly during landing on relatively short runways or in adverse weather conditions. By deploying the reversers on touchdown, you can reduce the reliance on the aircraft’s wheel brakes at higher speeds after touchdown.

16 Νοε 2020 · Reverse thrust, also known as thrust reversal, involves diverting the thrust of an aircraft's engines to decelerate the plane. When reverse thrust is active, it changes the direction of airflow emanating from the engine to help slow the aircraft down.
