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 ...
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.
Fast aircraft, for example military jets, may enter the pattern with a run-and-break (in the US, overhead maneuver or overhead break). The aircraft flies at speed along the final leg, and makes a sharp, high-G turn above midfield to lose speed and arrive on the downwind leg at pattern altitude and in landing configuration.
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]
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.
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 ...
So if an aircraft's wing area is increased by 10% and nothing else is changed, the takeoff speed will fall by about 5%. Likewise, if an aircraft designed to take off at 150 mph grows in weight during development by 40%, its takeoff speed increases to 150 1.4 {\displaystyle 150{\sqrt {1.4}}} ≈ 177 mph.
The extension behind the flight deck on the Rockwell B-1 Lancer and Boeing 747 was added to improve the cross-sectional area distribution according to the area rule. [17] Aircraft designed according to Whitcomb's area rule (such as the F-102 Delta Dagger and the Northrop F-5) looked odd when they first appeared and were sometimes dubbed "flying ...
