Umbra A.U.T. 18

TerryLeave a comment

The A.U.T.18 – the designation signifying Aeronautica Umbra S.A., the manufacturer, Ing Felice Trojani, the designer, and the originally-planned wing area of 18sq.m – was an all-metal stressed-skin single-seat fighter, one example of which was ordered in 1936 for evaluation by the Regia Aeronautica. Unusual among contemporary Italian single-seat fighters in having its armament of twin 12.7mm guns mounted in the wings, the A.U.T.18 was powered by a Fiat A.80 R.C.41 18-cylinder radial engine rated at 1030hp for take-off, and flew for the first time on 22 April 1939. Initial trials were performed with an NACA-type engine cowling, but this was supplanted from April 1940 by a close-fitting cowling with the rocker arms partly enclosed by fairings. Evaluation of the sole prototype was completed on 5 November 1940, when the aircraft was delivered to the Regia Aeronautica, but the Ministero dell’Aeronautica did not consider that the Trojani fighter offered any advantages over the Macchi C.200 and Fiat G.50, both of which were in production, and further development of the A.U.T.18 was discontinued.

The Urban Air UFM-13 Lambada is a two-seat side by side mid-wing motorglider / ultralight aeroplane. The UFM-13 Lambada is developed and built by Urban s.r.o. in Czech and is constructed from composite with sandwich construction. The prototype of the side-by-side two-seat Lambada flew first in May 1996. This UL-plane is a taildrager with quickly dismounting wings. The wings with a total wingspan of 12 meter, quickly to increase by mounting 2 x 1,5 meter wingtips into 15 meter, giving the Lambada excellent gliding performances.

The Samba XXL is based on successful plane UFM-10 Samba. Excellent flight characteristics were preserved while the space for pilots was extended. That is why Samba XXL is ideal for travelling, training and towing sail planes.
SAMBA XXL – brief technical description:
The ultra-light plane Samba XXL is a double-seat, single-engine, self-carrying low-wing aeroplane with crew members sitting one next to each other. It is all-composite. The fuselage is made mainly of carbon laminate with local sandwich construction. The wing is of sandwich construction while the flanges are of carbon rowing.
The wing is equipped with a lifting flap with a slot. Positions of electrically adjustable flaps are 20° for take-off and 45° for land. The tail surfaces are of classic layout. The carriage is three-wheel with controlled front wheel and braked main wheels.
The main carriage legs consist of a laminate spring. Integrated fuel tanks (2 x 50 litres) are located in the wing leading edge.
The plane may be equipped with a towing device for sail planes towing with maximal climbing weight of 650 kg.
The Samba XXL may be equipped with removable wing extensions. 2009 Price: 50000 EURO

United Helicopters J-5

To counteract torque this two-bladed-rotor experimental helicopter used not a conventional tail rotor but a jet thrust system. The latter consisted of a fan blower placed just behind the engine with a ‘stove pipe’ tail forward. Air was thus forced under pressure through the hollow fuselage into a tail orifice where vanes directed the jet thrust laterally.
Main rotor torque was effectively overcome, but this torque compensation system’s power requirements proved markedly excessive at speeds greater than 64km/h. Single-seat experimental helicopter with open frame front mounting pilot and engine and metal cone tail with jet thrust duct. One built.
