Abstract: A hydrogen fluoride/deuterium fluoride chemical laser having low concentration of deactivants is provided by the application of external heat rather than by internal combustion to cause thermal decomposition of the normal diatomic fluorine to convert it to atomic fluorine. This is accomplished by external heating of inert gases that then heat the diatomic fluorine or by directly heating from an external source the diatomic fluorine to form atomic fluorine. The formed atomic fluorine is then mixed with hydrogen and/or deuterium in a laser chamber to produce lasing of the gases when brought together in a conventional manner and therefrom a laser output.

Abstract: An instrument (reflectometer) for continuously measuring the reflectance perties of materials as a function of the angle of incidence in which a sample and a mirror are mounted on a rotating platform in such a manner that, as the angle of incidence on the sample is varied, the reflected radiation is always incident on a detector which is fixed with respect to the rotating platform. The angle of incidence on the sample is measured and used to drive an axis of an X-Y recorder. The angle of incidence on the mirror is measured and used to correct the detected signal for any errors introduced by the properties of the mirror. This corrected signal is then used to drive the other axis of the X-Y recorder to produce a plot of the reflection coefficients vs angle of incidence for the sample. For fixed angles of incidence on the sample the detector can be moved to produce a plot of the diffused reflections as a function of the angular deviation from the specular angle.

Abstract: A missile system in which a missile is guided in a predetermined trajectory rom launch or shortly thereafter in yaw by proportional navigation and in pitch first by a pitch programmer until said missile reaches a predetermined angle between a line of sight of a seeker of the missile and a centerline of the missile, then in pitch by a time optimal controller to direct the missile at a predetermined angle toward a target and finally by proportional navigation in pitch of the missile to the target.

Abstract: A valve consisting of a rotating flapper type valve which covers an inlet d outlet opening in a missile base and being held open by the insertion of an inlet fitting of a supply duct into the valve for supplying conditioned air into a missile and the valve having spring means biasing it in the closed direction against the action of the supply duct and latch means which latches the flapper type valve in the closed position when said supply duct has been removed from the air inlet opening of the valve.

Abstract: A rocket detent and release mechanism which restrains a rocket in a launch ube during transportation of the launch tube and rocket mounted on a transporting vehicle; the detent and release mechanism is of such structure as to be released on ignition of a rocket motor of the rocket to allow the rocket to be launched, and the detent and release mechanism is fabricated and mounted such that no tools are required for engaging the detent and release mechanism when mounting the rocket in the launch tube.

Abstract: The use of a class or compounds known as amine-boranes and their derivati in solid propellants to produce or generate hydrogen or deuterium upon combustion.

Abstract: A hypervelocity rocket system with velocity amplifier including a launch e with a projectile mounted therein by sabot means and a rocket motor with an energy absorber at one end and mounted in the launch tube for impacting the projectile and causing velocity amplification of the projectile through momentum transfer as it is propelled from the launch tube.

Abstract: A method for pressure testing a rocket motor case by inserting a movable ton in the nozzle end of the rocket motor case, sealing the piston relative to the throat of the rocket motor case and then applying pressure to the rocket motor case to pressure test the rocket motor case to a predetermined pressure or to failure.

Abstract: A system for intercepting a target with a missile having semi-active homing guidance. The target is discretely illuminated by a laser beam and the missile homes on the reflected illumination from the target.

Abstract: Filament/epoxy camouflage launch tubes in which the launch tubes are fabrted using conventional filament winding processes and materials and in which each tube is bonded together with an epoxy resin system in which the epoxy resin system includes coloring agents for coloring the launch tubes in a camouflage color that colors the launch tube through and through. The exact color of the launch tube can be varied by varying the amount of the coloring agent.

Abstract: A missile guidance system in which a projectile or missile is fired toward predetermined target with the missile being tracked on its flight toward the target by radar, processing the radar information in a computer apparatus and finally computing a new trajectory from the missile to the target and transmitting correction signals to a correction device on the missile including thrusters on the missile to cause the trajectory of the missile to be changed to the newly computed trajectory for the missile. This system corrects the trajectory of the missile while in flight by recomputing a trajectory from the missile to the predetermined target and making appropriate corrections each time. Thisenables the missile to only contain radar reflecting means, and correction detection and control means on the missile rather than having gyro and other type devices on board the missile which take up a considerable amount of space and weight.

Abstract: An image detection system in which a subject is supported in a position for a source of electromagnetic rays to traverse at least a portion of the subject and have the traversing rays picked up by a photointensifier which directly converts the electromagnetic rays to light rays by use of a fiber optic type scintillator converter, directly converts the light rays to a projected electronic image by a cathode face, intensifies the projected electronic image, converts the intensified electronic image back to light rays and finally displays the converted light rays on a display surface to provide a positive and vivid photographic type image of the traversing rays on the display surface.
