Microstar Variviggen
Burt Rutan design VariViggen started when he was a student at Cal Poly (California Polytechnic State University) in the early 1960s. He started building the prototype in his garage in 1968. After four years of work, the aircraft made its first flight 27 February 1972.
Leo Chagnes built the MicroStar based on plans of the VariViggen over four years.
The wing is styrofoam foam with epoxy coating and the fuselage is spruce and birch plywood. It is powered with 2 TRS18 Microturbo turbojet engines. Microturbo was responsible for the engine, with the completion of the frame, the calculation of the implementation and the centering of the two engines. This installation required a modification of the rear. The increase in surface area required a 20 cm increase.
The air inlets are fiberglass, and the cowling is made of sheet aluminium. The electronics are located just outside the engines, and is accessed by doors. The power units are separated from the airframe by three fire partitions.
The wheels are derived from a Cesna150 and the assembly is retractable via an electric servo coupled with a manual override. The luggage compartment behind the rear seat has been replaced by a 200 lt kerosene fuel tank, additional to two 35 lt tanks housed in the wings.
After more than 4 hours running and jumping fleas, Leo Chagnes made ​​the first flight on July 20, 1979.
Burt Rutan flew with Jacques Costes aboard MicroStar on December 19, 1981.
