Definitions
- This invention relates to a missile launcher for imparting spin to a missile during launch, and in particular, but not exclusively, to such a launcher for use on a helicopter.
- a missile launcher for imparting spin to a missile during launch and including a missile having a propulsion motor for generating propulsion efflux, structural support means, longitudinal guide means extending along a portion of the length of the missile for supporting and guiding the missile during launch and being rotatably mounted with respect to said structural support means, and efflux deflection means coupled to said longitudinal guide means whereby impingement of efflux from said propulsion means imparts spin to said missile.
- said missile launcher includes releasable locking means operable to effect locking of said missile against longitudinal movement with respect to said longitudinal guide means and to effect locking of said longitudinal guide means against rotational movement with respect to said structural support means.
- the arrangement illustrated is intended to be used to impart spin to a missile of the type containing a boost motor as it is launched fran a helicopter.
- a tubular outer support structure 1 is secured to a helicopter (not shown) by pylon 2.
- An inner launch tube 3 is rotatably mounted by means of bearings 4 and 5 within the tubular outer support structure.
- the inner launch tube 3 contains four equispaced guide blocks 15 (only three of which are shown) defining between each a longitudinal groove 8.
- the missile 6 is seated within the inner tube 3 with each of its four fins 7 slotted into one of the longitudinal grooves 8.
- a shallow groove 9 extends longitudinally along each guide block 15 to engage with command link receivers 10 on the missile.
- the two sets of grooves 8 and 9 in the inner launch tube 3 rotate the missile while at the same time allowing the missile to slide freely along the longitudinal axis of the inner launch tube 3.
- the guide blocks thus allow the missile to be fully supported by inner tube 3.
- the inner launch tube 3 extends beyond the rear end of tubular support structure 1 and supports at its end a multi-bladed impeller 11.
- a locking mechanism 12 locks the missile 6 and the tube 3 in position inside support structure 1 to prevent both
- the locking device 12 comprises an actuator mechanism 13 secured to the inner launch tube 3 and pins 14 projecting into bores provided in the missile body and the outer support structure 1.
- the actuator mechanism may be a solenoid or an explosive cutter for example that known as a 'Metron' cutter.
- the locking mechanism 12 is released to allow axial movement of the missile relative to the inner tube 3 and allow rotation of the tube 3 with respect to the outer support structure 1.
- the boost motor is ignited and the efflux exhausting rearwardly passes through the multi-bladed impeller 11 and is deflected.
- the reaction torque developed by the deflected thrust causes the inner launch tube 3 to rotate on bearings 4 and 5 and the inner tube 3 spins the missile around with it as it rotates.
- the missile 6 travels axially along tube 3 guided by the sets of grooves as shown at 8 and 9 until it emerges from the end of the tube.
- the missile leaves the launch tube smoothly and continues its flight with the spin imparted to it by the inner launch tube 3.
- the invention need not be limited to missiles of the type shown in the drawing. Missiles of other configurations could also be launched from the device, by making appropriate changes, without departing from the scope of this invention.
- the launcher may be used with missiles in which the longitudinal launch acceleration is imparted by an integral rocket motor.
- Containerised missiles may also be launched from the device.
- the missile container, complete with missile, could be slotted inside the inner launch tube 3 and the whole assembly rotated.
