A contract from RAE (Farnborough) to build a Binocular helmet mounted display system was received in July 1987. A similar system had previously been delivered to RARDE but that was monocular so duplication of the parts was necessary to give a binocular capability.
The system comprises a Mk 4 flying helmet with the two optical assemblies attached to it, an Electronics unit and a Pilot’s Control Panel. A junction box allows the Electronics unit to be sited remotely. The optical assemblies contain, as well as the necessary lenses, a one inch monochrome CRT.
The system was delivered in March 1988 and was installed together with the RAE’s Symbol Generator, Helmet Position Sensor and Image Intensifier Camera on the RAE Lynx experimental helicopter as part of a visually coupled system being assembled.
Another variant of this design was supplied for trials on a McDonnell-Douglas KC-10 air to air refueling tanker. A pair of Teledyne cameras gave a stereo image to assist the boom operator of the tanker to line up the boom. The system was in this case mounted on a ’skeleton’ framework helmet derived from an industrial ‘hard hat’. Yet another trial of this binocular system was made with General Dynamics Land Systems for use in an indirect viewing system for land vehicles.
