A method for the self-protection of an aircraft or the like against radar-guided missiles and a self-protection device for use in aircraft and the like against radar-guided missiles, which enables in-flight cutting and dispensing of chaff dipoles of a preselected length into the airstream along the flight path of the aircraft. The device comprises a housing enclosing a motor having a flywheel providing a motor inertia that enables the motor to maintain a substantially constant rotational speed when a load is applied, a magnetic clutch, gearing for rotating a platen roller and a cutter roller, as well as means for controlling the operation of the device, and an exit opening with a spoiler for dispensing the cut dipoles into the airstream.

A device for the in-flight cutting and dispensing of chaff dipoles into an airstream along the flight path of an aerial vehicle, which comprises: (a) a housing member enclosing the following elements (b)-(h); (b) a chaff roving storage compartment; (c) a drive motor having a rotatable drive shaft; (d) a flywheel affixed to the shaft enabling the shaft to maintain a substantially constant rotational speed when a dispense mode of the device is initiated; (e) a rotatable cutter roller connectable to the drive shaft; (f) a rotatable platen roller opposing the cutter roller; (g) a gear assembly for connecting the drive shaft to at least one of the rollers for rotating the at least one roller; (h) a clutch assembly for coupling and de-coupling the drive shaft to the gear assembly in response to a signal provided thereto; (i) control means for outputting a signal to the clutch assembly so as to activate the operation of the assembly and control the rotation of the at least one roller; (j) a braking mechanism for reducing the rotational speed of the at least one roller in response to a signal provided thereto; (k) guide means on an upstream side of the rollers for guiding chaff from the chaff roving compartment into the nip of rollers so that rotation of the at least one roller causes the chaff roving to pass between the rollers and be cut into dipoles of a preselected length; (l) an exit opening in a bottom side of the housing permitting cut dipoles to exit the device and pass into the airstream; and (m) a moveable bottom cover member attached to the bottom side of the housing for closing the opening when the device is not in use and for permitting the cut dipoles to exit the device into the airstream when cut dipoles are to be dispensed.
