1. A reconnaissance system capable of scanning an inaccessible target area and relaying the information to an observation point where it is displayed for visual observation comprising an infrared transducer means for converting detected infrared radiations into electrical signals proportional to the detected infrared radiations, transmitting means connected to said transducer means for transmitting electrical signals, rotating projectile means rotating at a predetermined rate enclosing said transmitting means and having said transducer means fixedly attached to the outer periphery of the projectile for scanning in a helical path the target area in a fixed rotating relationship with the projectile, at a rate equal to the rotating rate of said projectile receiving means for receiving and demodulating said electrical signals, and visual display means connected to said receiving means for converting electrical signals into a visual representation of the target area.

A free spinning gyroscope is provided which has a spin axis, together with precession means for precessing the gyroscope. In addition, means are provided for detecting an electromagnetic field of energy and adapted to generate signals indicative of misalignment of the gyroscope spin axis with the energy field. Means are provided for utilizing the generated signals to directly control the precessing means to align the gyroscope spin axis with the electromagnetic field of energy.

A overhead attack missile for targets of little movement such as tanks or firing turrets is described. It comprises: at least one hollow charge, with a unidirectional radial action possessing a pyrotechnic dissymmetry means such as the off-centering of the detonator of the charge to preserve the straightness of the burst despite the movement of the missile and a guidance means to bring the missile, at the end its course, overhead of the target. The invention is applied to any stabilized or unmanned aerial weapons carrying war heads.

A feedback PDM encoder and method is presented which permits utilization ofneumatic pulse duration modulation (PDM) actuators with potentiometer position pickoffs in a digital autopilot loop. The actuator is directly driven by a signal derived in the digital autopilot which is in the pulse duration modulation (PDM) format. This signal is derived within the autopilot digital computer using conventional digital techniques. Analog feedback from the potentiometer which indicates angular excursion of the actuator is formatted into a PDM format. This method yields all signals necessary to operate the actuator in a closed loop missile control system.

The present invention is a gun system which utilizes rocket assisted projectiles and accurately controls their placement. The projectile is fired by a gun and actual trajectory variables are compared in a computer with desired trajectory conditions. If there is a difference, the firing time of the rocket is altered to make the actual trajectory variable correspond to the desired condition. A radar system is utilized by the computer to obtain the trajectory information. A transmitter is connected to the computer to send the firing signal to a receiver mounted in the projectile.

This invention relates to a servocontrol system for a weapon such as a missile which is a shoulder-launched, infrared-homing, guided missile which provides frontline troops with effective air defense against low altitude enemy aircraft. The weapon, described herein for purposes of illustration, consists of a missile and launcher combination which can be readily transported and operated within the normal environments associated with ground forces in a combat area. To meet the size, weight, and performance requirements, the missile achieves passive homing guidance by using a space-stabilized, infrared-seeking-head control system to generate guidance signals for a single-channel, variable-incidence wing control system working in conjunction with a rolling airframe.
摘要:
A sensor system that measures flight motions with respect to a classical Euler angle system of coordinates by aligning itself with the plane of total angle of attack via a pendulum mass. The system permits a simple determination of lift and drag for a spinning vehicle at angle of attack whereby the measurements are used as inputs to a flight control system to control the motions of the spinning vehicle.
摘要:
An improved air-to-surface missile having a warhead which is confined solely to the lower half of the missile, and this half contains all the fragments which would normally be distributed throughout both halves of the missile. An upper casing portion need not be employed except to maintain symmetry and aerodynamic stability of the missile as a whole. In order to offset the slewing effect of the fragment pattern at the target on account of a low angle of approach, the fragmented lower surface of the warhead is flattened as it extends toward the rear end and is also curved upwardly so as to approach the longitudinal axis of the missile which contains the warhead.
