[62] [63] Jim Foreman produced the Bat-Glider plans for a Rogallo-wing hang glider and sold copies for US$5 throughout the world; later, Taras Kiceniuk, Tom Dickinson and two other team members made a similar hang glider called Batso and sold copies of its plans. The plans of these hang gliders circulated in some magazines in the mid-1960s.
The commercial availability of Dickenson's hang glider made the Rogallo wing very popular, and prompted several builders during the 1970s to attempt motorization of their flexible-wing aircraft [31] but unlike Barry Palmer – who placed the center of gravity well below the keel – most builders were mounting the engine to the wing, where a ...
His first and largest hang glider was about 45 pounds and had a surface area of 342 sq ft (31.8 m 2). Palmer explored control of his several versions of hang gliders by using different control frames : pilot in front of the control frame, pilot behind the control frame, and control frame in front of the pilot in a swing seat, which ...
An engine was installed by John Moody in 1975 so the glider could be launched from flat terrain. [1] [5] Early powered versions consisted simply of a motor added to the foot-launched hang glider version with control by a combination of weight shift for pitch and tip rudders for roll and yaw, with the tip rudders used together as air brakes.
The SunFun started as a foot-launched glider design, the VJ-24, and was developed into a wheeled undercarriage motor glider, the VJ-24W. The VJ-24 was derived from the earlier Volmer VJ-23 Swingwing and differed from that design by replacing the wooden structure with metal and employing a constant chord, strut-braced wing in place of the VJ-23's cantilever, tapered wing.
The prototype VJ-23 was completed late in 1971 and in an era when foot-launched aircraft were Rogallo-style hang gliders, the VJ-23 was described as more of a foot-launched sailplane, with three axis controls. Jensen and Culver collaborated on the design from a concern about the safety of weight shift hang gliders as well as their structural ...
The Ascender II+ was introduced in early 1982 and was aimed at the physically larger pilot. This redesigned model incorporated a wider 20-1/2 inch hang cage. All earlier models had a 15 + 3 ⁄ 4-inch-wide (400 mm) hang cage. It also had stronger upright struts and wing with 1-3/4 inch spars of 0.049 inch thickness, whereas all earlier models ...
Hang glider just after launch from Salève, France. Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised, fixed-wing heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth [1] to form a wing.
