Scheibe Falke
The Scheibe SF-25 Falke ( en, Falcon) is a German touring motor glider developed from the earlier Bergfalke glider by Scheibe Flugzeugbau. Since May 2006 the business has been run by Scheibe Aircraft GmbH. Development The company had produced the Motor Spatz but decided to produce a better light aircraft based on the Bergfalke glider. It had a new forward fuselage with an enclosed cockpit with two side-by-side seats and originally a Hirth F10A2a engine in the nose. It first flew in May 1963 as the SF-25A Motor Falke. After an initial batch of aircraft the wing was lowered and it was renamed as just the SF-25B Falke. A number of variants were built with various engines and the type was licence built by Sportavia-Putzer, Aeronautica Umbra (Italy), Loravia (France) and Slingsby (United Kingdom). The current model is the SF 25C. It is currently available with a choice of three engines: the Rotax 912 80 hp, the Rotax 912S (100 hp) and the Rotax 914F3 (115 hp). V ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

Motor Gliders
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in which he ...

Slingsby Falke
The Slingsby Type 61 Falke was a licence-built version of the Scheibe SF 25B Motor glider built by Slingsby Sailplanes. It entered service with the Royal Air Force for air cadet training as the Slingsby Venture. Development In 1970 Slingsby acquired a licence to build the SF 25B as the Type 61A Falke, a side-by-side two-seat dual training monoplane. This first variant was powered by a 45 hp Starck Stamo MS1500 engine and first flew at Wombleton on 8 February 1971. During May 1971 one aircraft was evaluated by the Royal Air Force as the Venture T1 and an order for 15 aircraft followed. The aircraft were to be operated by Volunteer Gliding Schools for basic air cadet training. Following replacement by the Grob Vigilant T1 they were all sold in 1990.

Tricycle Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172.
