TheGAF Jindivik is a radio-controlledtarget drone produced by the AustralianGovernment Aircraft Factories (GAF). The name is from anAboriginal Australian word meaning "the hunted one".[1] Two manually-controlled prototypes, were built as theGAF Pika (Project C[2]) as a proof of concept to test the aerodynamics, engine and radio control systems, serialledA92-1/2, 'B-1/2'. The radio-controlled Jindivik was initially designated the Project B and received serials in the A93 series. Pika is an Aboriginal Australian word meaningflier.[3]
The Jindivik was developed as a result of a bilateral agreement between Australia and the UK regarding guided missile testing. While the UK provided the missiles, Australia provided test facilities, such as theWoomera Test Range. As a result of the talks, Australia gained the contract for developing a target drone toMinistry of Supply specification E.7/48.[4] The specification called for an aircraft capable of a 15-minute sortie at 12,000 metres (40,000 ft). Development began in 1948,[5] with the first flight of the Pika in 1950[1] and the first flight of the Jindivik Mk.1 in August 1952.[5]
The manually piloted prototype, known as the Pika, had side air intakes (to make room for the cockpit) and retractable undercarriage operated from a pneumatic reservoir.[6] The remotely-piloted version, the Jindivik, followed the same basic form except that it had a single skid instead of an undercarriage and a dorsal air intake located where the Pika's cockpit was. The Jindivik Mk.1 was powered by anArmstrong Siddeley Adder (ASA.1) turbojet, which had been developed as a disposable engine for the project. Only 14 Mk.1s were ever made. The Mk.2 was powered by a 7.3 kilonewtons (1,640 lbf)[7]Armstrong Siddeley Viper engine. The Viper was also intended for a short lifespan – about 10 hours, but a "long life" version was also produced for conventional aircraft.[8]

The control systems were manufactured by various firms includingElliott Brothers,GEC and McMichael, with assistance from theRoyal Aircraft Establishment.[9] Control was maintained through an autopilot that received radio commands from the ground, rather than direct flight by a ground controller.[9] Eighteen commands could be issued to the autopilot with six further commands for the operation of other onboard equipment. The drone was launched via a self-steering trolley. At 110 knots (200 km/h; 130 mph), the drone was designed to apply its flaps, push the elevators up and release the trolley. Landing was made at 150–125 knots (278–232 km/h; 173–144 mph). Two controllers (azimuth and elevation) were used to align the drone on the runway. On landing it touched down on its skid and banking would cause the wingtip "shoes" to touch the runway, which controlled its path down the runway as it slowed.[8]
Between 1952 and 1986, a total of 502 aircraft were produced. Examples for use in the United Kingdom were shipped by surface transport, and assembled and tested byFairey Aviation atHayes, Middlesex, andManchester Airport. In 1997, the production line was re-opened to build another 15 for Britain.[10]
1 Pika and 22 Jindiviks are preserved as either in storage or on display in museums or collections around the world ( 1 in Sweden, 8 in UK, 13 in Australia).[13]
