摘要： A portable three-dimensional position and velocity data archiving system for use with an aircraft during flight testing and evaluations. The system includes a ground based system and an airborne system. Each system includes a GPS receiver electrically connected with a GPS antenna for receiving and interpreting GPS signals transmitted from a GPS satellite constellation. Each system also includes a radio communication device for transferring position and velocity data as well as error correction data and guidance cues between the ground and airborne systems. The portable system acquires, processes, archives, and provides precise three-dimensional position and velocity data for the aircraft in real time. Information regarding aircraft position, direction, velocity, acceleration and any correction needs referenced to a selected coordinate system is immediately presented to a vehicle piloting crew on analog as well as digital indicators.

摘要： A gun barrel shrouding system (11) is capable of significantly reducing the infrared signature of a gun barrel, without directly cooling the gun barrel. A shroud (21) is placed around the gun barrel, but the shroud (21) does not contact the gun barrel. Air is circulated through the shroud (21) to cool the shroud (21) itself, but the very hot gun barrel is only partially cooled by the air as the air exits the shroud (21). Since the shroud (21) does not contact the gun barrel, the shroud (21) may be manufactured of a lightweight and simple design, and the recoil action of the gun barrel upon firing does not need to be compensated for by the shroud (21).
摘要翻译：枪管罩系统（11）能够显着降低枪管的红外线特征，而不会直接冷却枪管。护罩（21）放置在枪管周围，但护罩（21）不接触枪管。空气通过护罩（21）循环以冷却护罩（21）本身，但是当空气离开护罩（21）时，非常热的枪管仅由空气部分地冷却。由于护罩（21）不接触枪管，护罩（21）可以由重量轻且简单的设计制造，并且枪管在击发时的反冲作用不需要被护罩（21）补偿）。

摘要： Composite articles are prepared by resin transfer molding and an applied gas pressure during heating. A mass of reinforcement is placed into a mold (22), and the mold (22) is evacuated. A resin source (36) is connected to the mold (22), and thermosetting resin is introduced into the mold (22) from the source (36). A gas pressure source (44) is connected to the mold (22), and an external column (40) of resin is maintained in the gas pressure line (46). The mold (22) is heated to set and cure the resin within the mold (22), but the resin in the external column (40) is maintained in an unset condition. After the resin is introduced into the mold (22) and simultaneously with the heating of the resin, a gas pressure is applied to the column (40) of liquid resin, preferably at a pressure greater than the vapor pressure of water at the temperature to which the resin is heated, to prevent gas evolution to form bubbles during setting and curing and to minimize the volume of any bubbles already present in the resin from other sources.

摘要： A piezoelectric actuator (1) includes a plurality of linearly axially expandable hard piezoelectric rods (8) located between two plates (4 and 6) and are distributed about a central twistable core (2) fastened between the plates (4 and 6), with the axis of the rods (8) skew to the axis of the core (2), resembling a squirrel cage. The actuator (1) produces a twisting movement between the plates (4 and 6), responsive to voltage induced expansion of those piezoelectric rods (8). Fly by Wire aircraft control is realized with the actuator (1) in various systems providing all electric control of aerodynamic surfaces (9), including an electronic helicopter swashplate (25 and 27) by which the effective pitch of the main rotor blade (3) is controlled.

摘要： A concentric face gear assembly includes a first face gear (50) having first face gear teeth and second face gear (45) having second face gear teeth. At least one input pinion (43) and at least one idler pinion (81) contact both face gears. The first face gear (50) directly drives a rotor, but the second face gear (45) does not directly drive a rotor. Since it does not drive a rotor, the second face gear (45) does not comprise a web or spline attachment and is therefore lightweight. Both face gears include thrust bearings (47, 52), which are located radially outwardly of the first face gear teeth and radially inwardly of the second face gear teeth. The first face gear (50) includes a web, which is relatively thin due to the thrust bearing (52) of the first face gear (50) being located radially outwardly of the first face gear teeth.
摘要翻译：同心面齿轮组件包括具有第一面齿轮齿的第一平面齿轮（50）和具有第二面齿轮齿的第二平面齿轮（45）。至少一个输入小齿轮（43）和至少一个惰轮（81）接触两个齿轮。第一平面齿轮（50）直接驱动转子，但是第二平面齿轮（45）不直接驱动转子。由于它不驱动转子，所以第二平面齿轮（45）不包括腹板或花键连接件，因此重量轻。两个平面齿轮包括推力轴承（47,52），它们位于第一面齿轮齿的径向外侧并且位于第二面齿轮齿的径向内侧。第一平面齿轮（50）包括腹板，由于第一面齿轮（50）的推力轴承（52）位于第一面齿轮齿的径向外侧，腹板相对较薄。
