[ Ссылка ] – UL Power, Ellipse Experimental Aircraft, Sport Aviation Expo Jan 25th 28th 2017 Sebring Florida.
UL Power sells eight airplane engines ranging from 97 hp up to 200 hp. All are dual electronic ignition, fuel injection and FADEC. The Ellipse Spirit powered by the UL Power engine is a carbon – kevlar honeycomb design, equipped by unique elliptic wing with integrated slot.
The wing may be equipped by optional aerodynamic speed brakes. Side sticks controls and roomy cabin / 120 cm (47 in) provide high comfort, flaps and trim surfaces are electrically operated in standard.
Extremely rigid composite airframe has been obviously tested for flutter. During the flutter testing the oscillation was agitated at a true airspeed of V=465 km/h (at altitude of 4000m). With security factor is calculated flutter limit up to TAS= 172 kts (318 km/h).
Airplane is designed for maximum design speed VD 350 km/hr (190 kts) and all versions for MTOM of 600 kg, tested for g-load of 12g. Max cruising speed is 275km/h, great advantage is uncompromising max speed in turbulence Vra 255km/h, highest in this category. A retractable landing gear (trailing link type, electrically driven) or fixed gear, is offered.
The airframe is designed to meet all the requirements in compliance with German regulations LTF-UL for „Ultralight Aircraft“, European regulations for CS-LSA (light sport aeroplanes), U.S.FAR 23 and US LSA specification for design and performance for „Ultralight and Experimental Light Sport Aircraft“.
