Description: Palo Alto, CA: Hiller Aircraft Corporation, 1958. Photograph. Ex-Library. B&W Illustrations; This is a group of ephemera relating to the release and promotion of the X-18 "Propelloplane".

"Stanley Hiller, then seventeen, established the first helicopter factory on the West Coast of the United States, located in Berkeley, California, in 1942, under the name "Hiller Industries," to develop his design for the coaxial-rotor XH-44 "Hiller-Copter" for the U. S. Army. The XH-44 became operational in 1944. In collaboration with Henry J. Kaiser, it became United Helicopters in 1945. In the postwar years, United Helicopter produced a number of innovative helicopter designs for military and civilian purposes, including coaxial-rotor and tailless designs, as well as more conventional models. In January, 1949, a Hiller 360 became the first civilian helicopter to cross the United States. Besides helicopters, in the year after World War II, Stanley Hiller researched a two-man rocket-jet aircraft design that took off and landed vertically, called the VJ-100, in which he tried unsuccessfully to interest the U. S. Military." (from Wikipedia) "The Hiller X-18 was an experimental cargo transport aircraft designed to be the first testbed for tiltwing and V/STOL (vertical/short takeoff and landing) technology. Design work started in 1955 by Stanley Hiller Jr and Hiller Aircraft Corporation received a manufacturing contract and funding from the U. S. Air Force to build the only X-18 ever produced, serialled 57-3078. To speed up construction and conserve money, the plane was constructed from scavenged parts including a Chase YC-122C Avitruc fuselage, 49-2883, and turboprops from the Lockheed XFV-1 and Convair XFY-1 Pogo experimental fighter programs. The tri-bladed contra-rotating propellers were a giant 16 ft (4.8 m) across. The Westinghouse turbojet engine had its exhaust diverted upwards and downwards at the tail to give the plane pitch control at low speeds. Hiller nicknamed their X-18 the Propelloplane for public relations purposes." (from Wikipedia). Very Good+ .
