Aerial Warfare Patents (Class 434/14)
  • Patent number: 9584232
    Abstract: A computer simulates flight routes for simulated airborne transmitters across a spatial region divided into unit area tiles and over time based on actual aircraft flight plan data. The computer determines transmitter counts per tile per time interval based on the flight routes and assigns transmit parameters, including transmit message rates, to the transmitters. The computer determines transmit message rates per tile based on the transmitter counts and the transmit parameters. The computer generates, for a simulated receiver, an antenna pattern covering at least some of the tiles, and converts the transmit message rates of the covered tiles to a total effective receive message rate of interfering messages at the receiver. The computer determines a probability of successful detection of a desired message among the interfering messages at the receiver based on the effective receive message rate.

  • Patent number: 8834163
    Abstract: A network connects stations in a distributed physics based simulation system. When the simulation detects that a weapon, especially a missile or directed energy beam, is engaging a target vehicle, one physics station determines damage status of the target vehicle. The detonation or strike of the weapon is applied to a model of the vehicle composed of pieces each made up of a number of parts. Where the damage to a piece of the vehicle exceeds a predetermined threshold, the piece is removed from the vehicle, and where a predetermined maximum damage is reached for the vehicle, the vehicle is considered destroyed. The damage assessment from the weapon is made using raytracing in a physics engine that is also used to control movement of virtual objects in the simulation according to rules of physics of the physics engine.

  • Patent number: 6763325
    Abstract: Enhanced realism of a real-time simulator having multiple computer-controlled units results from making the units capable of reacting to only those other units that each of them can be aware of because of their spatial relationships to the unit. Awareness is based upon probabilities; it can persist after a relationship changes; and it can be influenced by a unit's designation of a target. Each unit selects a target based upon a score incorporating multiple aspects of its tactical situation, and can change targets when the situation changes. A unit selects a strategy in response to which of a set of tactical configurations exist between the unit and its target; the strategy can change short of completion when the configuration changes. A plan produces guidance commands from the high-level strategy. The guidance commands are converted into control settings for guiding the subject unit using a physics engine for simulating the physical dynamics of the unit.

  • Patent number: 5308022
    Abstract: Kinematic data is generated onboard an aircraft for describing its state of motion as it flies over a tracking range. The kinematic data is transmitted to a plurality of remote stations on the tracking range and tracking data is generated which represents the actual state vector of the flying aircraft. Also generated is pseudo tracking data, identical to the tracking data but delayed in time, for representing the motion and trajectory of a pseudo aircraft. Utilizing the pseudo tracking data an image of the flying aircraft is generated from the viewpoint of the cockpit of the pseudo aircraft. A person may then view the image to observe the dynamics of the flying aircraft as if the person were chasing the actual aircraft in the pseudo aircraft. The method permits sophisticated maneuvers in the remote piloting of aircraft as well as flight performance analysis.

  • Patent number: 5002490
    Abstract: A system to simulate in-flight aircraft combat includes an energy sensitive switch intermediate a power source and signal generator. The switch has a first state which prevents the transmission of current from the power source to the signal generator and a second state which permits current to flow from the power source to the signal generator. The switch changes state when exposed to a given level of energy and permits current to flow to the signal generator which indicates a "hit". In a first embodiment, a sight is provided to align the attacking aircraft with the target. A trigger mechanism is mounted in the attacking aircraft which initiates the transmission of current from the power source to the signal generator. The optical switch changes state in response to exposure to energy emitted from an energy source mounted on the target. The pilot of the attacking aircraft trips the trigger when the target is aligned relative to the sight.

  • Patent number: 4729737
    Abstract: A system for training aircrews, particularly aircrews of relatively slow-moving aircraft such as helicopters in laser/electronic warfare countermeasure tactics and the use of laser/electronic warfare countermeasure equipment is provided. The system is operable with the aircraft's instruments to present the simulated threats whenever such threats are both with the line-of-sight of, and within the presentation range of the aircraft. Accordingly, such a system includes a plurality of independently operating threat-simulating transmitter units simulating both stationary and non-stationary threats by broadcasting omnidirectional radio frequency signals over a common carrier frequency. On-board equipment, carried on the aircraft determines whether the aircraft is both within the line-of-sight and within presentation range to the threat based upon receipt of the transmitter unit signals and the location of the threats relative to that of the aircraft.

  • Patent number: 4308015
    Abstract: A system for aircraft gunnery training and accuracy evaluation wherein a head-up display unit employs a cathode ray tube for projecting simulated bullets on a pilot's sighting panel. The simulated bullets each comprise a pair of bullet trajectory indicia simulating the firing of the guns of the aircraft at an actual target. The indicia in a pair of bullet trajectory indicia are equidistantly spaced from the simulated trajectory path by an amount related to a selected dimension of the target. Each pair of bullet trajectory indicia are initially displayed to reflect the physical conditions of the aircraft at the time of firing, including the rates of aircraft roll, pitch and yaw, the aircraft lift acceleration, true aircraft airspeed, gun angle of attack, and relative air density. As the bullet trajectory indicia traverse the simulated trajectory path, the separation between the indicia comprising a pair of indicia is decreased to simulate increasing distance from the firing aircraft.
