  2. Thrust - Wikipedia

    en.wikipedia.org/wiki/Thrust

    The thrust axis for an airplane is the line of action of the total thrust at any instant. It depends on the location, number, and characteristics of the jet engines or propellers. It depends on the location, number, and characteristics of the jet engines or propellers.

  3. Thrust-to-weight ratio - Wikipedia

    en.wikipedia.org/wiki/Thrust-to-weight_ratio

    A plane can take off even if the thrust is less than its weight as, unlike a rocket, the lifting force is produced by lift from the wings, not directly by thrust from the engine. As long as the aircraft can produce enough thrust to travel at a horizontal speed above its stall speed, the wings will produce enough lift to counter the weight of ...

  4. Aircraft flight mechanics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_mechanics

    In flight a powered aircraft can be considered as being acted on by four forces: lift, weight, thrust, and drag. [1] Thrust is the force generated by the engine (whether that engine be a jet engine, a propeller, or -- in exotic cases such as the X-15-- a rocket) and acts in a forward direction for the purpose of overcoming drag. [2]

  5. Airplane - Wikipedia

    en.wikipedia.org/wiki/Airplane

    An airplane (North American English) or aeroplane (British English), informally plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations .

  6. Thrust reversal - Wikipedia

    en.wikipedia.org/wiki/Thrust_reversal

    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 ...

  7. Jet engine - Wikipedia

    en.wikipedia.org/wiki/Jet_engine

    The thrust-to-weight ratio of jet engines with similar configurations varies with scale, but is mostly a function of engine construction technology. For a given engine, the lighter the engine, the better the thrust-to-weight is, the less fuel is used to compensate for drag due to the lift needed to carry the engine weight, or to accelerate the ...

  8. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    Also, the direction of the force of thrust is generally fixed in the body frame, though some aircraft can vary this direction, for example by thrust vectoring. The wind frame is a convenient frame to express the aerodynamic forces and moments acting on an aircraft.

  9. Jet engine performance - Wikipedia

    en.wikipedia.org/wiki/Jet_engine_performance

    Thrust from the rear mount plane was a Boeing requirement. [130] Compared to the 15,000 lb thrust JT3D with its four structural cases the 40,000 lb thrust JT9D made economical use of supporting structure with only three structural cases making a compact lightweight design. [131]
