    Abstract: The invention provides a liquid fueled pulsed detonation air breathing engine. The engine has at least one, and preferably a multiplicity of, detonation chambers, each of which has an inlet end for opening and receiving a charge of fuel and air, and an outlet end for discharging combustion product gases. A fast-acting valve is located above the inlet ends of the detonation chambers and cyclically opens the fuel and air receiving openings in the inlet ends of the detonation chambers to allow a fuel/air charge to enter the chambers. In a preferred embodiment, the valve is of a rotary type with a body that has at least one opening through which fuel and air can flow into the inlet end of the detonation chamber. Once the valve has closed, detonation is initiated by an ignitor and impulse force is provided by the resultant shock wave. Thereafter, the valve opens again so that the detonation chamber can be charged with fuel and air to recommence the cycle. The invention also provides an embodiment of an engine that has both inlet and outlet valves. These valves operate out of phase so that when the inlet valve is open to receive fuel and air into the detonation chamber, the outlet valve is closed. When detonation commences, the outlet valve is open and the inlet valve is closed. Optionally, a source of oxygen allows a stratified charge in the engine to enhance detonation. Also provided is a control system (48) for sensing the position of the valves, (58, 80) and using this sensed position to inject fuel, inject oxygen and ignite the fuel and air mixture.

    Abstract: Method and apparatus for compaction of powder of high density boron nitride, having an initial particle diameter of at least two microns, into a high density crystal aggregate of between 1 mm up to about 1 cm in diameter, the resulting crystal aggregate having a zincblende form, the wurtzite form or mixtures of the zincblende and wurtzite forms. High density aggregates of boron nitride, preferably having particle sizes with diameters at least 2 .mu.m, are placed in a hollow, substantially cylindrical first container of metal, and the first container is surrounded by a fluid-like material of metal or metal powder having a shock wave velocity V. The first container and fluid-like material are placed in a substantially cylindrical second container that is purged of substantially all air and sealed. The second container has a rigid side wall and two rigid end walls. A high explosive, having a detonation velocity D of at least 6 km/sec and preferably at least 8 km/sec, is positioned at one end wall and along at least a portion of the side wall of the second container. The high explosive is detonated, and an approximately radially directed pressure wave moves through the fluid-like material and the boron nitride powder toward the center of the second container. A second, approximately radially directed pressure wave, separated in time from the first pressure wave, subsequently moves outward through the fluid-like material and the boron nitride powder. These two pressure waves produce boron nitride aggregates of density at least 95 percent of the theoretical maximum density (3.49 gm/cm.sup.3) and of sizes at least 1 mm in diameter. A solid mandrel can be positioned near a center line of the second container to improve the quality of the resulting product. Grain sizes as small as 0.005-0.05 gm are produced. Boron nitride aggregates with Knoop hardness parameters in the range of 4300-5000 Kgm/mm.sup.2 can be produced in this manner.

    Abstract: Apparatus for improving properties of a solid material by providing shock waves therein. A laser oscillator 10a provides a plurality of pulses 112 of coherent radiation. The leading edge of each pulse is sharpened either by a metal foil 18 or by phase conjugation reflection means 18a, 18e including a stimulated Brillouin scattering cell 18d,18e and optionally a Faraday isolator 18b. Each pulse is directed onto an amplifier 123 comprising first and second laser amplifier rods 23a,23b in series. At least a major portion of the radiation 112 amplified by the first amplifier rod 23a is directed to the second amplifier rod 23b, where it is amplified and then directed to a surface of the solid material. Substantially uniform spatial amplitude is achieved in the radiation 112 in at least one of these ways: A pair of flashlamps 70,71 are included with each laser amplifier rod 23a,23b for pumping the rod; the axis of each flashlamp 70,71 and the axis of the first rod 23a are substantially parallel to each other and substantially in the same (first) plane; and a (second) plane containing the axis of the second rod 23b and the parallel axes of its associated flashlamps 70,71 is substantially perpendicular to the first plane; and/or the oscillator 10c provides a beam of unpolarized coherent radiation 12T in which the spatial amplitude pattern of each succeeding pulse is substantially a mirror image of the pattern in the pulse that preceded it, or is rotated about its axis by a predetermined smaller angle from the pattern in the pulse that preceded it.
