Mosquito (303)

The Mosquito is the first Glasflügel aircraft whose maiden flight Eugen Hänle did not live to see after his accident in September 1975.

The Mosquito was flown for the first time on February 20, 1976 by Josef Prasser on the Hahnweide and was the second German aircraft of the new 15 meter class.

For the first time, the cooperation between Schempp-Hirth and Glasflügel had an effect in practice with the Mosquito, because the Mini-Nimbus from Holighaus used the wing of the Mosquito. The special feature of this flapped wing is the combined air brake and flap, which goes back to an initiative of Eugen Hänle. The new system allows the brake to change in a certain area without affecting the flap.

When landing, the brake flap is then fully open upwards and the flap is fully down. Normal flap deflections with superimposed ailerons are possible with the closed trailing edge rotary brake flap from 7 degrees negative to 10 degrees downwards.

The fuselage and the tail units come from the Hornet and the 203. What is new is that the canopy opens upwards to the front and is one piece. The Mosquito used the FX67-K-150 profile.

From the beginning of 1976 to May 1980, a total of 101 Mosquitos with wing-fuselage transitions and 98 Mosquitos B without wing-fuselage transitions and lower empty mass were built.

The Prototype is in Southern Germany today.
