- Airfoil leading edge with cavity
- Patent number: 5836549
Abstract: A jet airplane capable of supersonic flight has airfoils with leading edges. Each leading edge has a cavity which extends for substantially the entire length of the airfoil. The leading edge also has a cover which is approximately the same size as the cavity. The cover has an open position and a closed position. When the cover is in the open position, the leading portion has a concave profile. When the cover is in the closed position, the leading portion has a convex profile that gives the airfoil a conventional shape. The cover is rotated to the open position when the airplane reaches supersonic speed. At supersonic speed, a shock wave forms on the leading edge of the airfoil. However, the cavity forms a compression zone between the shock wave and the leading edge, diverting the heat and pressure of the shock wave away from the airfoil. Downstream from the compressed zone, pressure wakes form along the airfoil and cool the airfoil.

- Aircraft engine nozzle
- Patent number: 5775635
Abstract: An aircraft engine has a nozzle shaped to reduce the volume of Mach diamonds being formed in the exhaust plume. A notch or recess is formed in the discharge edge of the nozzle. The recess provides a forward discharge edge that causes additional Mach diamonds to occur at a regular spacing from the forward discharge edge. These additional Mach diamonds are axially staggered with other Mach diamonds, which occur at regular spacing from the rearward edge of the nozzle discharge edge. Each Mach diamond has a volume that is substantially less than one-half the volume of a Mach diamond created by a conventional nozzle. This results in less high temperature areas per axial increment in the plume than the prior art exhaust plumes. Because Mach diamonds are the primary cause of high infrared emissions, as well as acoustic noise, a reduction in the total volume of Mach diamonds in the exhaust plume thus reduces infrared emissions, as well as the noise.

- Method and apparatus for filter infrared emission
- Patent number: 5726798
Abstract: A method and apparatus are provided for emitting a laser like monochromatic narrow beam of light at a selected wavelength from a heated emitter member having a plurality of parallel layers while reducing emission at other wavelengths of light. The parallel layers are overlaid with each other. Each of the parallel layers extends transversely for a particular width. A heat source stimulates the emitter member to emit photons, which are determined by the composition of materials within the emitter member. The emitter member emits monochromatic light at a selected wavelength in response to the photon emissions. The selected wavelength of the monochromatic light is determined by the width of the layers of the emitter member. Light at other wavelengths does not transmit through and their emissivity also decreases.

- Radiation communication system
- Patent number: 5680135
Abstract: An aircraft has an exhaust flame or plume which can be modulated to communicate. A sound emitter is mounted to the aircraft for emitting acoustic waves into the exhaust plume. An encoder will control the emitter at selected digital sequence to provide a digital message. The flame or plume will radiate at a frequency range of interest depending on the type of aircraft. The sound waves cause the frequencies to change from a continuous spectrum to a spectrum which has a much lower amplitude. A detector remotely located from the aircraft will detect radiation. It filters frequencies outside of the frequency range of interest. It will discriminate between the modulated pattern and the continuous pattern. This output provides the digital code that was encoded by the encoder. A decoder will decode the message for the recipient.

- Object detector
- Patent number: 5543917
Abstract: A method for detecting objects while eliminating unwanted background utilizes polarizing contrasts. A lens systems focuses light from the field of view through a beam splitter. One beam passes to a digitizer through a polarizer which polarizes the beam at one angle. The other beam is reflected to another polarizer, which is located at a 90.degree. angle relative to the first polarizer. The pixels from the polarized images are digitized. A processor compares the corresponding pixels, subtracting one from the other to find a polarizing contrast. A range that can be varied will display only those pixels which have polarizing contrasts within the selected range. The selection of the range will either include or eliminate the background while displaying man-made targets.

- Position identification device using an accelerometer
- Patent number: 5492010
Abstract: A device for determining position uses three voltage dividers. Each voltage divider is a metal conductor having a head on one end and two legs on an opposite end. The tips of the legs of each of the bodies are located in planes which are perpendicular to the other bodies. A DC voltage is applied to the head of each of the bodies to create first and second electron flow paths. The voltage across each flow path is monitored. A difference in voltage of flow path relative to the other indicates a change in velocity in a direction wherein one leg leads the other leg. The voltage change correlates to acceleration. By timing the duration, velocity and distance travelled are computed. When mounted aboard a plane, vehicle, ship or spacecraft the unit displays a continous "present location".

- Object locator
- Patent number: 5452089
Abstract: A search light employs variable polarization angles to enhance target identification. The search light shines a beam of light which may be directed across terrain. The beam of light is alternated in polarization angles at a rate of about five to twelve cycles per second. The alternating contrast in polarization angles produces flashing to an observer viewing certain targets struck by the beam of light. The flashing appears when striking man-made objects which tend to have a differential in polarized light between horizontal and vertical polarization. Natural objects do not appear to provide the flashing to the observer. The rotating polarization angles are accomplished in one instance by using a stationary polarizer and a liquid crystal retarder mounted in front of a light source. In another instance, the change in polarization angles is accomplished by rotating a polarizer in front of a light source. The light source may be infrared, visible or ultraviolet.

- Wave attenuation
- Patent number: 5420588
Abstract: A radar cross-section reduction system utilizes a charging device for creating a high positive DC static potential on an object such as an aircraft. The charging system is mounted to the object so that this DC potential would be applied to the outer skin or surface of the object. The charging system includes Van de Graaf generators located in housings attached to the object. Each Van de Graaf generator has two pulleys about which a belt is rotated. One of the pulleys and the belt are nonconductors, while the other pulley is a conductor. This results in a buildup of positive charges at one end of the belt and negative charges at the other end. The negative charges are picked off and applied to a ground section. The positive charges are picked off and applied to a collector. The collector is in electrical continuity with the outer structure of the object. Negative dissipators attached to the ground section dissipate the excess negative charges during flight.

- Object detector
- Patent number: 5404225
Abstract: A device will assist in detecting man-made objects by using a liquid crystal retarder and a stationary polarizer. The liquid crystal retarder shifts impinging light 90 degrees between a nonrotated and a rotated mode. In the nonrotated mode, the retarder is essentially transparent, with the light passing through the retarder and through the polarizer. In the rotated mode, the impinging light will be rotated 90 degrees. An observer viewing the light passing through the polarizer will detect a difference or a flashing, with the rate depending upon the speed of oscillation between the rotated and nonrotated modes. The system can be employed with visible light optical systems such as binoculars, or with an infrared detector or video camera.

- Laser apparatus
- Patent number: 5384802
Abstract: A laser device utilizes a turbojet engine to provide a stimulation source. The turbojet engine is conventional, having a compression section, a fuel injection and igniting section, and an afterburner section. A pair of mirrors are mounted adjacent the hot gaseous stream produced by the turbojet engine. One of the mirrors is fully reflective and the other is partially reflective. The mirrors face each other and are perpendicular to the flow of the gaseous stream, creating a reflection path that is transverse to the flow. The high temperature creates excited molecules in the gaseous stream. This results in photons being emitted, which when striking other excited atoms which emit photons of the same wavelength, create additional photons to combine into a laser beam travelling along a reflection path between the mirrors. A portion of the laser beam passes through the partially reflecting mirror where it strikes an inclined mirror that aims the beam toward a desired target.

- Object discriminator
- Patent number: 5345308
Abstract: A device will detect man-made objects by using a polarizer mounted to a video camera. The polarizer rotates about an axis in front of a lens array of the video camera. The rotation of the polarizer alternately polarizes light received in proportion to the speed of rotation. This produces flashing in intensity for detecting the object as well as background rejection due to its lack of polarization. A man-made object having both horizontal and vertical surfaces of a type that will reflect light that can be polarized will provide flashing through the lens array as the polarizer passes through horizontal and vertical position. On the other hand, backgrounds don't have polarized components and won't flash. Attention is drawn to the man-made target. A high pass filter between the video signal processor and the monitor reduces background from the observed scene, permitting precise lock-on to the target.
