The Pilatus SB-1 was a development project by the Swiss company Pilatus Flugzeugwerke AG and the ETH Zurich , but no aircraft were built by it. The name Pilatus SB-1 is composed of the aircraft manufacturer, the Pilatus Flugzeugwerke, the abbreviation SB stands for Swiss mountain aircraft.
history
The 1939 project SB-1 was intended as a purely experimental aircraft; commercial use was not intended. The SB-1 was to be a middle-decker with space for a pilot and an observer, who sit next to each other in the cockpit, and two passengers directly behind. The pilot and passenger compartment was in front of the wing. The fuselage should consist largely of covered tubular steel grating. The aircraft should be powered by a single motor located at the center of gravity of the fuselage under the wing box. The positioning of the engine significantly restricted the size of the cargo hold, which was arranged above the wing box. A two-bladed propeller should be driven by V-belts and tensioning pulleys on each of the unearthed blades. It was hoped that the installation of the motor in the fuselage and the power transmission via V-belt would result in low air resistance and at the same time favorable slow flight characteristics due to the air flow of the propellers acting directly on the leading edge of the wing. The aircraft was designed as a middle-decker with a rigid tail wheel landing gear and a conventional tail unit. It was also considered to install two motors in the fuselage with the same design. So that each propeller is driven by its own motor. However, a clutch was provided so that if one engine failed, the power of the still functioning engine could be applied to both propellers. The concept with the engine in the middle of the fuselage and the power transmission via V-belts or belts did not prove to be useful in the long term. Therefore, the project was terminated and the development of the SB-2 moved on. When the SB-1 was being planned, it was not yet clear who would build the aircraft, so it is not entirely clear whether Pilatus would actually have built it. The Farnerwerke were also considered as a producer. However, there is a high probability that the SB-1, like the Pilatus SB-2 and the planned Pilatus SB-5, would also have been built by Pilatus.
