The Volmer VJ-23 Swingwing is an American high-wing, single-seat, foot launched glider that was designed by Irv Culver and built by Volmer Jensen and supplied as plans by his company Volmer Aircraft for amateur construction. Kits were also available from DSK Aircraft. [1] [2]

Design and development

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 integrity. [1] [2]

The aircraft is predominantly made from wood and covered in doped Ceconite. The wing leading edge is made from poplar plywood and supported by nose ribs made from marine-grade plywood. The wing spar cap strips and tail ribs are fashioned from spruce. The tailboom is an aluminium tube. Its wing is cantilevered and tapered from wing root to wing tip. The VJ-23 lands and takes off on foot, but the aircraft is equipped with small wheels to allow it to be pulled up a hill. The aircraft's rigid wing structure requires that it be transported in a trailer, rather than rolled up and carried on a roof rack like a hang glider. [1] [2]

To make construction easier and quicker the design was developed into the aluminium tube, strut-braced Volmer VJ-24 SunFun. [1]

Both the glider and powered VJ-24E version proved popular and a large number were built. [2]

Operational history

One VJ-23E was flown across the English Channel. [2]

History of hang gliding

Hang gliding is an air sport employing a foot-launchable aircraft known as a hang glider. Typically, a modern hang glider is constructed of an aluminium alloy or composite-framed fabric wing. The pilot is ensconced in a harness suspended from the airframe, and exercises control by shifting body weight in opposition to a control frame.

Powered hang glider Foot-launched powered hang glider

A foot-launched powered hang glider (FLPHG), also called powered harness, nanolight, or hangmotor, is a powered hang glider harness with a motor and propeller in pusher configuration. An ordinary hang glider is used for its wing and control frame, and the pilot can foot-launch from a hill or from flat ground, needing a length of about a football field to get airborne, or much less if there is an oncoming breeze and no obstacles.

Schneider Grunau Baby German single-seat glider, 1931

The Schneider Grunau Baby was a single-seat sailplane first built in Germany in 1931, with some 6,000 examples constructed in some 20 countries. It was relatively easy to build from plans, it flew well, and the aircraft was strong enough to handle mild aerobatics and the occasional hard landing. When the Baby first appeared, it was accepted wisdom that the pilot should feel as much unimpeded airflow as possible, to better sense rising and falling currents of air and temperature changes etc.
