Pedal Shaker Assembly

Notes:

This Unit is part of the Flight Control system and is put into operation when the onset of a stall is detected. The system uses the Angle of Attack Transmitter mounted on the nose and other inputs such as gear and flap position and when it senses an impending stall it will activate the Shaker. The Shaker is an electric motor with an eccentric or cam built in that causes it to vibrate rather coarsely. On the EAP the Shaker is attached to one Rudder Pedal to provide the pilot with a physical warning that the aircraft is approaching a stall.
Marconi Avionics, in common with other suppliers, made equipment for the EAP at their own cost in anticipation of orders for the Typhoon. Around 6 to 8 sets of equipment were made and all were put through the full evaluation/qualification tests.

EAP stands for "Experimental Aircraft Programme and was a technology demonstrator for what was to become the Eurofighter Typhoon. The sole aircraft (serial ZF534) first flew on 8 August 1986. The EAP aircraft was retired from service on 1 May 1991 and was then sent to the Aeronautical and Automotive Engineering department of Loughborough University, but, as of April 2012, it has been moved to the Royal Air Force Museum Cosford.

Marconi Avionics, in common with other suppliers, made equipment for the EAP at their own cost in anticipation of orders for the Typhoon. The items supplied included the Head Up Display, Air Data Computer, Flight Control Computer, Pilot’s Control Panel, Pilot’s Stick, Pedal Shaker Quadruplex Position Sensors and the Baro Set Panel. Around 6 to 8 sets of equipment were made and all were put through the full evaluation/qualification tests.
