  • Patent number: 7642491
    Abstract: An aircraft 1 with a spiral inducing assembly 2 which is capable of inducing the aircraft to travel in a continuous spiraling motion without the aircraft rolling. A ramjet 6b is attached to a tube 3 that is able to rotate around the encircled part of the fuselage. The ramjet 6b is able to rotate in a pivoting manner on the rotate-able tube 3 with respect to the rotate-able tube 3, thereby changing their pitch relative to the longitudinal axis of the rotate-able tube 3. Ramjet 6b is smaller than another ramjet on the right side of the tube 3. The difference in size between the ramjets makes the ramjet 6b exert a weaker force on the rotate-able tube 3 than the ramjet on the right side when the ramjets are rotated in the same direction. The imbalance between the rotational forces thus causes the rotate-able tube 3 to rotate. A fin 6c is also able to cause the rotate-able tube 3 to rotate during flight. When rotated, the ramjets would exert a lateral force on the rotate-able tube 3.

    Abstract: An aircraft 1 with a spiral inducing assembly 2 which is capable of inducing the aircraft to travel in a continuous spiraling motion without the aircraft rolling. A ramjet 6b is attached to a tube 3a that is able to rotate around the encircled part of the fuselage. The ramjet 6b is able to rotate in a pivoting manner on the rotate-able tube 3a with respect to the rotate-able tube 3a, thereby changing their pitch relative to the longitudinal axis of the rotate-able tube 3a. Ramjet 6b is rotated as is another ramjet on the right side of the tube 3a. The rotate-able tube 3a is rotated by means of an electric motor 3b rotating a wheel 3c.

  • Publication number: 20090294582
    Abstract: A lighter-than-air aircraft is propelled via a bending-rotating tail whip. Two actuating areas located on opposite sides in a rear area of a lifting gas body are shortened by activated actuators. A vertical plane of symmetry of the lifting gas body and thus, the lifting gas body itself, are pivoted in an area of bending zones about angles a and ?. An activated state exists when the actuator performs work for propelling the aircraft. Propulsion can be provided by deformation of the lifting gas body. Changes in direction can also be effected by asymmetrical sequences of movements.

  • Patent number: 6808145
    Abstract: The present invention includes a method for a dual-mode propulsion system. During the first mode of operation, intake air is liquefied through a cooling heat exchanger and condenser using a combination of stored liquid hydrogen (LH2) and stored liquid nitrogen (LN2) as coolants. The liquefied air is then separated into separated liquid oxygen (SLO2) and separated liquid nitrogen (SLN2), which may contain molecules of each other or other elements commonly found in air. The stored liquid nitrogen is replaced with SLO2, while the SLN2 is pumped back through the system with the stored nitrogen in a regeneration process. The SLN2, LN2, and LH2 become gaseous as they pass through the condenser and heat exchanger and are burned in the dual mode rocket thrust chamber to produce thrust. In the second mode, the same thrust chamber is operated as a liquid hydrogen-oxygen rocket, where the liquid oxygen is the SLO2 collected during the first mode.

  • Publication number: 20030197093
    Abstract: This invention relates to a magnetic vortex generator which has the ability to generate negative mass and a negative spring constant which, according to Einstein's General Theory of Relativity, is required in order to create a stable wormhole between our space and hyperspace. Two separate, but electrically connected, toroidal coils of differing radii, carry magnetic flux in opposite directions about their common centerline. According to Maxwell's equation, this produces bucking electric fields along said centerline. Because the two solenoids have different radii, the parallel spring constant of both coils is negative. The negative mass together with the negative spring constant produce a real resonant frequency which can distort the spacetime curvature due to the creation of powerful spikes of negative mass. This phenomenon, similar to the common electrical thunderstorm, opens up a wormhole into hyperspace through which low-density hyperspace energy can enter into our dimension.

  • Publication number: 20030192988
    Abstract: A propulsion device which takes advantage of the fact that the mass of an object will decrease if the energy density of the object changes rapidly. The energy density is changed by causing rapid mechanical deformations of the object. By these means, the mass of a rotating object is decreased to one side of its axis of rotation, creating an unbalanced centrifugal force that acts on the rotating object as a propulsive force in the direction from the lower mass half toward the higher mass half. The propulsive force is used to propel an object or hold an object in position in opposition to an outside force or provide mechanical energy for a purpose such as the generation of electricity.

  • Publication number: 20030057319
    Abstract: A propulsion device which takes advantage of the fact that the mass of an object will decrease if the energy density of the object changes rapidly. The energy density is changed by exposing the object to a rapidly changing electric field or magnetic field or by causing the object to experience quantum mechanical tunneling. By these means, the mass of a rotating object is decreased to one side of the axis of rotation, creating an unbalanced centrifugal force that acts on the rotating object as a propulsive force in the direction from the lower mass half to the higher mass half. The propulsive force is used to propel an object or hold an object in position in opposition to an outside force or provide mechanical energy for a purpose such as the generation of electricity.

  • Patent number: 6536708
    Abstract: A take-off device includes a telescopic arrangement of three pipes arranged in a frame. The telescopic arrangement can pivot to a limited extent. The frame is mounted on a horizontal axis running through a center of gravity of the device and a centroidal axis of a lift of an airplane wing, whereby the frame can pivot around the axis. Forces exerted between the telescopic arrangement and the frame are transmitted via a bushing wedged on an outer pipe of the three pipes. A compressed gas accumulator can be opened by means of an actuating pressure signal, whereupon the telescopic arrangement extends outward. A bottom portion of an innermost tube knocks against a fixed point on the ground, which allows the airplane to accelerate to a lift-off speed. After the telescopic arrangement has extended outward, the telescopic arrangement retracts inward using a compressed gas stored in a pressure chamber.

  • Patent number: 6488233
    Abstract: Provided is a laser propelled craft having a) a forebody or nose, b) a tapering parabolic afterbody optic or mirror, c) a shroud mounted therebetween and extending aft to define an annular space around a portion of the afterbody near its base and d) means to transmit a pulsed laser beam toward the laser craft and afterbody optic and thence to focus into the annular shroud. The laser beam is pulsed to heat and pressurize the air in the annular space to expand same and propel such craft, the afterbody and shroud being so shaped as to self center or remain in the laser beam as the craft is propelled thereby. Such craft, which is spin-stablized, can also carry a fuel insert ring mounted in the shroud around the afterbody, to be ablated by the laser beam at a desired altitude, so as to transition from an air breathing craft to a rocket craft, when the atmospheric density becomes too low, e.g., at 30 km altitude so that the lasercraft can thereafter be propelled into, e.g., low earth orbit.

  • Patent number: 6405976
    Abstract: A lift and propulsion device is presented which utilizes Bournelli's Principle and the principle of relative motion to create lift. A series of discs are arranged in coaxial alignment. Each successive disc rotates in a direction opposite from the direction of rotation of the disc above it. Air is introduced at the lower outer circumferential surface of the first disc. The introduction of air at this point, as well as the relative motion of the counter-rotating surfaces between the first and second discs creates a large amount of lift. Air is introduced onto the opposite outer circumferential lower surface of the second disc, in the direction of rotation of the second disc. The introduction of this air creates a large amount of lift between Discs B and C. Each successive disc rotates in an opposite direction from the disc above it and has air interjected onto the lower circumferential surface of that disc in the direction of rotation of the disc.

  • Patent number: 6367739
    Abstract: A compound exhaust system including two or more stages, preferably three, uses the force of exhaust gases traveling from a thrust generating source through the exhaust system to maximize thrust and minimize wasted energy consumption. In particular, the compound exhaust system for a thrust generating source comprises at least a first stage exhaust and a smaller, second stage exhaust. Various reflections of high speed traveling gases are provided and the resultant pressures induced during this travel supplement the thrust provided by the thrust generating source, which can be a jet engine. The invention also relates to a novel airframe that uses multiple engines having the inventive compound exhaust system.

  • Patent number: 6364253
    Abstract: An airborne remote piloted vehicle does not require onboard fuel to greatly extend its endurance and payload capability. Photovoltaic cells are provided on substantially the entire bottom surface of the RPV to receive high intensity radiation beamed up from a ground station. The photovoltaic cells can be made responsive to visible light, infrared light and/or ultraviolet light emitted from lasers that direct narrow, high energy beams, or other directable narrow beams of other wavelengths of high energy radiation, including but not limited to microwaves. The cells convert the beamed up radiation to power at least one electrical motor driven propeller and instrumentation for onboard components including sensors, lasers, radio transmitters, and associated instrumentations. Control signals may also be beamed up or otherwise transmitted to the vehicle to control its transport to and hovering at an on-station location and to activate the onboard components for reconnaissance, monitoring, and relaying data.

  • Patent number: 6347766
    Abstract: Mach's principle and local Lorentz-invariance together yield the prediction of transient rest mass fluctuations in accelerated objects. These restmass fluctuations, in both principle and practice, can be quite large and, in principle at least, negative. They suggest that exotic space time transport devices may be feasible, the least exotic being “impulse engines”, devices that can produce accelerations without ejecting any material exhaust. Such “impulse engines” rely on inducing transient mass fluctuations in conventional electrical circuit components and combining them with a mechanically coupled pulsed thrust to produce propulsive forces without the ejection of any propellant. The invention comprises a method of producing propellant-less thrust by using force transducers (piezoelectric devices or their magnetic equivalents) attached to resonant mechanical structures.

  • Patent number: 6193194
    Abstract: A traveling-field, magnetic propulsion system and operating method is provided for achieving economical space travel. The system is based upon designing the vehicle in the form of a single-stage streamlined circular toroidal airfoil containing a thin-walled superconducting solenoid. It is initially launched vertically off the earth's surface into a vacuum environment at 125 km using conventional rocket propulsion. It is then accelerated along a high-inclination trajectory by a traveling repulsive magnetic field generated by ejecting an easily ionizable low-density gas cloud in the vehicle's magnetic field and transmitting a high-power, plane-polarized, microwave beam at the cloud tuned to the electron cyclotron resonant frequency. The transmitter is constructed horizontally on the earth's surface as an electronically-steered, phased array several hundred meters in diameter energized by a large superconducting energy storage system.
