A hydraulic cantilever tail lift on the back of a truck Four stages of deployment on an ambulance tail lift Control for a tail lift. A tail lift (term used in the UK, also called a "liftgate" in North America) is a mechanical device permanently installed on the rear of a work truck, van, or lorry, and is designed to facilitate the handling of goods from ground level or a loading dock to the ...
Tommy Gate is an American brand of hydraulic liftgate, or tail lift, manufactured by Woodbine Manufacturing Company. The company was formed in 1965 by Delbert "Bus" Brown and its production facility is located in Woodbine, Iowa .
Since the tail is operating in the flowfield of the wing, changes in the wing incidence cause changes in the downwash, but there is a delay for the change in wing flowfield to affect the tail lift, this is represented as a moment proportional to the rate of change of incidence: ˙
Over the years the business passed through name changes and ownership (Burtonwood Engineering, US Industries, Ratcliff Tail Lifts). John Ratcliff(former Variety Club Cheif Barker and Ted's son) owned the business with sister Marsha up to a few years ago. Other Manufactuers: Tommy Lift, Maxon, Ross & Bonnyman.
Ducted fan tail rotors have also been used in the Russian Kamov Ka-60 medium-lift helicopter, [17] and also on the Japanese military's Kawasaki OH-1 Ninja reconnaissance rotorcraft. French light helicopter manufacturer Hélicoptères Guimbal has also used a Fenestron for their Guimbal Cabri G2 , a compact reciprocating engine-powered rotorcraft ...
Stabilator or all-moving tail: In transonic flight shock waves generated by the front of the tailplane render any elevator unusable. An all-moving tail was developed by the British for the Miles M.52 , but first saw actual transonic flight on the Bell X-1 ; Bell Aircraft Corporation had included an elevator trim device that could alter the ...
An elevon that is not part of the main wing, but instead is a separate tail surface, is a stabilator (but stabilators are also used for pitch control only, with no roll function, as on the Piper Cherokee series of aircraft). Elevons are installed on each side of the aircraft at the trailing edge of the wing.
Longitudinal dihedral can also mean the angle between the zero-lift axis of the wing and the zero-lift axis of the horizontal tail instead of between the root chords of the two surfaces. This is the more meaningful usage because the directions of zero-lift are pertinent to trim and stability while the directions of the root chords are not.
