  • Patent number: 11513072
    Abstract: A real-time ablation sensor uses an optical detector, such as a spectrometer or radiometer, to detect ablation of a material, for example by detecting a signal indicative of ablation of the material, which may be an engineered material. The optical detector may detect reflected light, either from the material being ablated, or from products of the ablation, such as in the vicinity of the material being ablated. A light source may be used to provide light that is reflected by the material and/or the ablation products, with the reflected light received by the detector. The light may be of a selected wavelength or wavelengths, with the selection made in combination with the selection/configuration of the material to be ablated, and/or the selection/configuration of the optical detector.

    Abstract: A system includes a target illumination laser (TIL) configured to illuminate an airborne target with a TIL beam. The system also includes a beacon illuminator (BIL) configured to transmit a spot of illumination to an expected location on the target, wherein the spot of illumination is more focused than the TIL beam. The system also includes a camera configured to receive an image of the spot reflected off the target. The system also includes a controller configured to determine an actual location of the spot on the target based on the received image. The controller is also configured to estimate a spot motion by correlating the actual location of the spot on the target with the expected location on the target. The controller is also configured to predict uplink jitter of a high energy laser (HEL) beam generated by a HEL based on the BIL spot motion, the uplink jitter caused by atmospheric optical turbulence.

  • Patent number: 11512669
    Abstract: A rocket engine nozzle manufacturable and applicable to tactical missile designs includes an aerospike having a plurality of airfoil fins distributed around a central longitudinal axis of a rocket engine combustion chamber. The aerospike is integrated on an exit plane at an exit end of the combustion chamber. The airfoil fins and an inner perimeter of the combustion chamber define a plurality of apertures which choke an airflow exiting the combustion chamber and cause the airflow to expand supersonically along the airfoil fins. The aerospike rocket engine nozzle requires less machine precision and achieves packing benefits over conventional bell and aerospike nozzle geometries. The configuration of the aerospike rocket engine nozzle also removes the producibility and heating constraints typically encountered with conventional aerospike nozzles in tactical missile applications while improving thrust performance of the rocket engine across a wide range of altitudes.

  • Patent number: 11499505
    Abstract: A flight test system uses a flight termination destruct charge that is configured to overpressurize a pressure vessel in a rocket motor to terminate thrust. The flight termination destruct charge is an electroexplosive detonator arranged on a final burn surface of a propellant contained in the pressure chamber. In a multi-pulse rocket motor, one of the pulses is ignited by the activation of the detonator. The activated detonator is configured to ignite the propellant grain without venting of the gas resulting from the burning of the propellant. Due to the burning of the propellant, the surface area in the pressure vessel is increased which causes increased pressure in the pressure vessel until a critical pressure is reached. When the critical pressure is reached, the rocket motor casing structural capabilities are exceeded. The overpressurized rocket motor casing then ruptures and thrust of the rocket motor is terminated.

  • Patent number: 11500109
    Abstract: A computer architecture for geolocation spoofing/meaconing detection is disclosed. According to some aspects, a computer accesses an incoming geolocation positioning signal. The computer determines, using a signal characteristics calculation subsystem, geolocation positioning signal characteristics for the incoming geolocation positioning signal. The computer provides, using a geolocation positioning spoofing/meaconing detection subsystem, the geolocation positioning signal characteristics as an input vector to a neural network, wherein the neural network determines whether the incoming geolocation positioning signal is legitimate or fake. If the incoming geolocation positioning signal is determined to be fake: the computer computes, using a Bayesian inference subsystem, a likelihood and a severity of a geolocation positioning technology based attack. The computer provides, as a digital transmission, an indication of whether the incoming geolocation positioning signal is legitimate or fake.

  • Patent number: 11502422
    Abstract: A datalink such as used on high-speed vehicles (missiles, guided-projectiles, manned or unmanned aircraft) includes an integrated conformal antenna array and out-of-band rejection filter for use with an RF radio. Integration of a single rejection filter between the EME power received by the antenna array and the coaxial RF connector effectively protects the connector as well as the radio. The connector can now be designed based solely on the transmit power requirements of the radio. The resultant connector is smaller and takes up less space inside the vehicle.
