These models are used in wind tunnel testing to gather data for the design of full-scale aircraft. [2] They are made in a wide array of sizes, ranging from miniature versions to those exceeding five feet in length. Some model aircraft are scaled to size. For example, a 1:40 scale that is 1/40th the size of the real aircraft. [1]
When an aircraft is stationary with the propeller spinning (in calm air), the relative wind vector for each propeller blade is from the side. However, as the aircraft starts to move forward, the relative wind vector comes increasingly from the front. The propeller blade pitch must be increased to maintain optimum angle of attack to the relative ...
Frog was a well-known British brand of flying model aircraft and scale model construction kits from the 1930s to the 1970s. The company's first model, an Interceptor Mk. 4, was launched in 1932, followed in 1936 by a range of 1:72 scale model aircraft kits made from cellulose acetate, which were the world's first.
A folding propeller is a type of propeller whose blades automatically fold out when the engine is turning, and then fold back (or "feather") when the engine stops. Folding propellers are found on sailing yachts, on model airplanes, and increasingly on self-launching gliders and small motor gliders, such as the Aériane Swift PAS.
