Bird dispersal apparatus.

摘要

Apparatus primarily for bird dispersal purposes at an airport in which remote control means (1) is provided for controlling operation of one or more sound emitting devices (4) adapted to cause a detonation or emit a detonation like sound at a required position or positions, e.g. in relation to an airport runway. The control is such that after a sound emission the device or each device (4) is ready for further operation. Each device (4) may consist of a combustion chamber (40) having an outlet (400) the remote control means (1) including a timer (2) for initiating admission of fuel such as propane gas into the chamber (4) for a predetermined period followed by automatic ignition of the fuel/air mixture for detonation thereof. The remote control (1) includes provision for selective operation of the devices (4) at different positions, e.g. adjacent a runway and also provision for runway or other location selection at which the devices (4) are positioned. Alternatively or additionally sound emitting devices may be provided which give an amplified play back of recorded detonation.
