One of the most unusual V/STOL aircraft programs was the Avro VZ-9 “Avrocar”. Designed to be a true flying saucer, the Avrocar was one of the few V/STOL aircraft to be developed in complete secrecy. Despite significant design changes during flight test, the Avrocar was unable to achieve its objectives and the program was ultimately canceled after the expenditure of over $10 million (1954-61). The concept of a lift fan driven by a turbojet engine did not die either, and lives on today as a key component of the Lockheed X-35 Joint Strike Fighter contender. While the Avrocar was under development, Peter Kappus of General Electric independently developed a lift fan propulsion system which evolved into the GE/Ryan VZ-11 (later XV-5) “Vertifan”.
