Deflected slipstream is an approach to creating an aircraft that can take off and land vertically (), or at least with a very short runway ().The basic principle is to deflect the slipstream from one or more propellers approximately 90 degrees, to create an upward thrust for vertical takeoff and a downward air cushion for landing.
Maximum landing gear operating speed. This is the maximum speed at which the landing gear on a retractable gear aircraft should be extended or retracted. [7] [9] [20] V LOF: Lift-off speed. [7] [9] V MC: Minimum control speed. The minimum speed at which the aircraft is still controllable with the critical engine inoperative. [7]
Speedtwin Developments had taken over the aircraft in 2000 and in 2012 announced the new name of Comet 1. E2E stands for "Engineered to excel". E2E stands for "Engineered to excel". At this time future developments including a retracting undercarriage, armament and turbo-prop engines were planned; the original idea of offering kits for home ...
An increase in weight increases the stall speed of the aircraft. Therefore, the landing approach speed increases as the aircraft's weight increases. The kinetic energy ( 1 / 2 mV 2) that has to be dissipated to stop an aircraft is a function of the mass of the aircraft and the square of its speed at touchdown. The kinetic energy ...
The higher the speed of the aircraft, the easier it is to counteract the yawing moment using the aircraft's controls. [8] The minimum control speed is the airspeed below which the force the rudder or ailerons can apply to the aircraft is not large enough to counteract the asymmetrical thrust at a maximum power setting.
Spiral slipstream, also known as propwash, prop wash, or spiraling slipstream, is a spiral-shaped slipstream formed behind a rotating propeller on an aircraft. The most noticeable effect resulting from the formation of a spiral slipstream is the tendency to yaw nose-left at low speed and full throttle (in centerline tractor aircraft with a ...
The pilot must make sure that the plane's nose is low enough to keep airspeed up. [5] However, airframe speed limits such as V A and V FE must be observed. [6] A forward-slip is useful when a pilot has set up for a landing approach with excessive height or must descend steeply beyond a tree line to touchdown near the runway threshold.
Though the Twin-60 was one of many 1920s two-seaters, its design was far from typical, with novel features driven by the aims of low running costs, easy maintenance, safety and the ability to use very basic landing grounds. The latter required short take-off distances, high climb rates, low landing speeds under good control and wheel brakes.
