The H38 Observer is an experimental design for an observation aircraft designed by Wolf Hoffmann, in Austria, in the early 1980s.

Design and development

At ILA 1984 in Hanover Wolf Hoffmann presented a mock-up for a new project based on the Hoffmann Dimona motor-glider, called Hoffmann Visonar, before being renamed.[1][2][3] The Observer's design aim was long endurance with minimal fuel burn, combined with extremely good vision from the cockpit. To obtain this, the conventional tractor propeller is driven by a mid-mounted engine placed behind the two side-by-side seats. This location for the power-plant was intended to leave the nose clear of obstruction. Since the canopy glazing extends to the crew's feet, vision was expected to be far better than from a conventional aircraft, and not far from that from some helicopters.[4]

The wings, rear fuselage and T-tail were identical to those of the Dimona, but with wing span increased. A choice of two engine options was proposed and provisions for versions with extended range were made for both options.

The project was not realized due to financial dispute with his former Austrian partner Hoffmann Aircraft and subsequent failure of finding a manufacturer for the H38 (as well as for the H40).[4]
