SZD 20 Wampire II Flying Wing by Jilles Smits

This aircraft has taken some time to get flying in a manner that I consider to be correct – COG is critical in getting the Wampir to fly.

It is not a model glider that I would recommend for a nervous modeller or pilot. There is quite a comprehensive build thread here with lots of info on setting up. The plan designed By Jilles Smitts has reproduced the very unusual glider impeccably.

The prototype was test flown by Steve Holland whom immediately after landing it said ” I just have to have one of these.”

Scale: 1/3 Wingspan: 5Mtr Weight: 22Lb

Designed for 5 channel radio control.

Video of the maiden flight can be seen here.
And here you can see a video of gliding at “Hells Mouth” in North Wales, some footage of the Wampire can be found in this at 2mins 50secs.

Description

The SZD-20X Wampir II Flying Wing

The Wampire II was designed to compare a flying wing designed to Standard class rules with a more conventional standard class glider. Main designer was Jan Dyrek.

Based on experience with the earlier SZD-6X Nietoperz and SZD-13 Wampir tail-less gliders, the SZD-20X was an all wood flying wing, with the pilot sitting in a pod extending aft of the trailing edge on the centreline, and large swept fins & rudders at approx 2/3 span on each wing.

The

SZD-20X

Early flight trials commenced with hops towed behind a car to test control responses, followed by an aero-tow launch on 9 September 1959, piloted by Adam Zientek. Flight trials revealed a marked sensitivity to turbulence resulting in flutter, and during trials at stalling speed, the SZD-20X entered a spin, which the rudders were unable to recover the aircraft from. Only when the pilot shifted his weight as far forward as he could did the SZD-20X recover from the spin.

Flying in the SZD-20X continued until 6 October 1959, when turbulence-induced flutter tore the aircraft apart, with the pilot escaping via parachute.
