Lilienthal Bekas X-32 / X-34
JAI / Jordan Aerospace Industries RumBird X-32 / GulfBird X-34
The Lilienthal Bekas (Lilienthal Snipe in English, Лиленталь Х-32 Беҝас in Russian) is a 2/3 seat, high wing single engine pusher ultralight from Ukraine.
The Lilienthal Bekas is a pod and boom, multi-purpose, pusher configuration ultralight with a high wing and low-set boom carrying a T-tail. The well glazed pod seats two in tandem and carries the constant chord wing at its top. The wing is braced to the lower fuselage by two pairs of cross braced struts and is fitted with flaps, which have a maximum deflection of 40°. A fixed, tricycle undercarriage with a castoring nosewheel is mounted on the pod.
The engine is mounted at the rear top of the pod, behind the cabin; types in the 60-100 hp (45-75 kW) range may be fitted, most commonly Rotax two or four cylinder models such as the Rotax 582 or 912UL and 912ULS. The engine is cowled on some aircraft but not all. Much of the slim boom is occupied by a broad chord fin with a straight swept leading edge. On some aircraft it is extended forwards with a fillet. The rudder hinge, also slightly swept, is at the end of the boom. The tailplane is of constant chord and braced to the end of the boom by a strut on each side.
The X-32 Bekas first flew in March 1993 and received its Ukrainian certification in 1995. The Rotax 582 and 912 variants were certified in 2003 and 2005 respectively. The aircraft has JAR-VLA certification.
Between 2003 and 2006, the X-32 and X-34 were marketed by JAI (Jordan Aerospace Industries) as the RumBird X-32 and GulfBird X-34. By 2009, more than 400 X-32s had been sold.
