This invention provides a shock mitigation means that attenuates the high frequency energy transmitted to the floating element of an inertial measurement unit (IMU) device in a cannon launched guided projectile or cannon launched munition improving the ability of the IMU to survive the extreme forces of such cannon launched environment. The invention utilizes a crushable foam mitigator located in the IMU device's housing to interfere and apply a compressive force to the floating element of the IMU device, plus a rubber pad attenuator element placed above the foam mitigator to further tailor the transmission of shock energy to the floating element in the IMU device.

Means for improving inertial measurement unit reliability for cannon launched applications

A hardened subminiature telemetry and sensor system for a ballistic projectile having a radome, antenna, steel insert, S-band transmitter circuit board, data recorder, sensor or measurement device and battery. The entire assembly is contained in such a way that the assembly can be threaded into the existing tracer well of a kinetic energy projectile.

Hardened subminiture telemetry and sensor system for a ballistic projectile

A system which is packaged within a projectile fuze body and obtains data relative to the projectile during a launch. Sensors are provided which obtain in-bore data as well as in-flight data. The in-bore data is recorded at a fast rate during in-bore travel of the projectile and is read out, continuously, at a slower rate during in-flight travel. Both in-bore data and in-flight data are encoded and transmitted to a ground station for analysis.

Aeroballistic diagnostic system

A payload carrying device which is inserted into a remote area of interest by means of a projectile carrier to obtain data, or the like, from the remote area. The device has counter rotating main blades as well as tail blades carried on a tail rotor. The particular payload is carried in a canister which may also include a power source, a command and control unit and a motor, if hover or lateral flight is desired. The pitch of the tail blades is variable as well as their orientation around an axis, the combination of which generates a thrust vector in a particular direction for controlled lateral flight.
