Device, method and system for extending range and improving tracking precision of mortar rounds

A system, device and method provide a glide kit that can attach to a conventional mortar round to create a glide-enabled round. The glide-enabled round can fit within a mortar tube. When the munition exits the mortar tube, it sequentially deploys wings and canards to initiate the glide maneuver and increase the mortar range. A state estimator subsystem can be employed with a canard control subsystem to actively guide the mortar to a fixed location. The combination of the estimator and canard control subsystems improves the tracking precision of the mortar round.

Control surfaces for use with high speed vehicles, and associated systems and methods

Vehicles with control surfaces and associated systems and methods are disclosed. In a particular embodiment, a rocket can include a plurality of bidirectional control surfaces positioned toward an aft portion of the rocket. In this embodiment, the bidirectional control surfaces can be operable to control the orientation and/or flight path of the rocket during both ascent, in a nose-first orientation, and descent, in a tail-first orientation for, e.g., a tail-down landing. Launch vehicles with fixed and deployable deceleration surfaces and associated systems and methods are also disclosed.

20170343327 · 2017-11-30 ·

A system of missile control surfaces includes a control surface housing, a control surface shaft which is rotatably mounted in the control surface housing, a control surface secured on the control surface shaft, a control surface drive and a coupling unit. The coupling unit couples the control surface drive to the control surface shaft in such a way that a movement of the control surface drive produces a rotation of the control surface shaft. To enable high forces to be applied reliably to a guided missile control surface, it is proposed that the coupling unit has at least one flexible tension element, which is secured on the control surface drive and is rolled up onto the control surface shaft to a certain extent.
