The "aerial screw" was one of several aerial machines drawn by Leonardo, including an early parachute, an ornithopter and a hang glider. The pen-and-ink sketch outlines an idea for a flying machine similar to a modern helicopter , with a spiral rotor or "aerial screw" based on a water screw , but intended to push against the fluid of the air ...
[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.
Richard Miller flying his new Bamboo Butterfly hang glider. Vista Del Mar California, 1966. Palmer experimented with about 8 different hang glider versions and their wings were mostly 90 degree swept back wings. His smallest glider weighed 24 lb (11 kg), and had a surface area of 205 sq ft (19.0 m 2). The flexibility in the frame caused no ...
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.
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 ...
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 Wasp SP Mk2 is a British powered hang glider that was designed and produced by Wasp Systems (now called Wasp Flight Systems) of Crook, Cumbria. Now out of production, when it was available the aircraft was supplied complete and ready-to-fly. [1] The SP Mk2 was introduced at Telford in 2002, following a 12-month development schedule. [1]
The Condor was designed as a flight training glider specifically to introduce new pilots to hang gliding. As such it has a very large wing area, low wing loading, a stall speed of 13 mph (21 km/h) and it is intended for use only under very light wind conditions. It was specifically intended for sale only to professional hang gliding instructors ...
