Glasflugel 304

Glasflugel 402




Intended to succeed the Mosquito B, the 15m span Glasfliigel 304 single-seater is a new design very similar to the Mosquito, work on which began in the autumn of 1979 by a team under Martin Hansen.
Construction is of glassfibre, with no carbon-fibre employed, although the 304/17 (now known as the Glasflugel 402), which has detachable wing tips to give a span of 17m, has largely carbon-fibre wing tips. It employs a new 16.4% thickness/chord ratio wing profile developed by Akaflieg Braunschweig and extensively tested and refined on a Mosquito. It features Glasflugel trailing edge dice brakes and interconnected variable camber flaps, a parrallogram control stick, T-tail with fixed stabilizer and elevator, and automatic connection on assembly of all flight control. The fuselage is similar to the Mosquito's but with a more pointed nose; the monowheel is retractable. The instrument panel can be tipped up, together with the front-hinged upwards opening canopy, with which it is integral, to allow the pilot more unobstructed entry. Up to 253lb of water ballast can be carried.

The prototype, D-9304, first flew on 10 May 1980. Production of the 304 started in the spring of 1981.
