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.
Effective February 15, 2007, the FAA ruled that US-registered twin-engine airplane operators can fly more than 180-minute ETOPS to the design limit of the aircraft. In November 2009, the Airbus A330 became the first aircraft to receive ETOPS-240 approval, which has since been offered by Airbus as an option.
The use of a T-tail on the Model 76 met with mixed critical reception when the aircraft was introduced. Plane & Pilot pronounced: "Outstanding design characteristics of the new Duchess include an aerodynamically advantageous T-tail, which places the horizontal surfaces above the propeller slipstream for better stability and handling.", [10] while Gerald Foster said: "[Beechcraft's] interest in ...
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 craft was said by its inventors that, in December 1922, it made a flight lasting 15 minutes, rising to an altitude of 6 ft (1.8 m). [5] [6] Contemporary newspaper reports from July 1923 indicated that the craft would be undergoing formal testing at Curtiss Field (now known as Columbia Field), near Mineola, Long Island, New York, however the outcome of those tests are not known.
Video obtained by CNN shows the plane landing hard on the runway, with the plane’s rear landing gear buckling and the right wing soon shearing away in a fireball. The fuselage rolled over as it ...
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". At this time future developments including a retracting undercarriage, armament and turbo-prop engines were planned; the original idea of offering kits for home building had been withdrawn. [1]
The aircraft was an Experimental Amateur Built Air Creation Twin aircraft, the National Transportation Safety Board said in a statement Sunday. Experimental aircraft crashes in Arizona, killing 1 ...
