摘要： An electromechanical actuator is provided for converting rotary action into linear action, and includes an electric motor, a cable yoke, an output shaft, and a pair of cables. The electric motor is adapted to be selectively energized and is configured, upon being energized to generate a drive torque. The cable yoke is coupled to receive the drive torque and is configured, upon receipt thereof, to rotate about a rotational axis. The output shaft is coupled to receive a drive force and is configured, upon receipt thereof, to translate along a linear axis that is disposed at least substantially perpendicular to the rotational axis. Each cable is wound, in pretension, on a portion of the cable yoke and around a portion of the output shaft. The pair of cables is configured, upon rotation of the cable yoke, to supply the drive force to the output shaft.

摘要： A gas thruster is configured to supply thrust over a relatively wide range, from a relatively low value to a relatively high thrust value, and exhibits relatively fine minimum impulse bit (MIB) performance. The gas thruster includes a thrust nozzle, a main stage, a main valve element, and a pilot valve. The gas thruster responds to thruster control signals supplied to the pilot valve and is configured such that for commands of relatively short duration, only the pilot valve responds and relatively low thrust is produced. Conversely, for command or relatively longer duration, the pilot valve and main valve element both respond and relatively higher thrust is produced.

摘要： An active pilot inceptor system includes a pilot inceptor, a multi-phase motor, and a motor control. The pilot inceptor is configured to receive user input and is operable, in response to the user input, to move to a control position. The multi-phase motor is coupled to the pilot inceptor to selectively supply haptic feedback thereto. The motor control is operable to selectively energize the multi-phase motor in a manner that causes the multi-phase motor to generate torque and supply the haptic feedback to the inceptor, and to selectively energize the multi-phase motor in a manner that the multi-phase motor does not generate torque.

摘要： A cured ablative composite assembly comprises a housing enclosing a pair of ablative composite sub-assemblies joined by a film adhesive. The cured ablative composite assembly is made by surface treating both ablative composite sub-assemblies in preparation for joining; coupling one ablative composite sub-assembly to another ablative composite sub-assembly with a film adhesive and enclosing the uncured ablative composite assembly within a housing; and depositing the combination of the housing and uncured ablative composite assembly in a ventilated oven with a load applied to the combination housing and uncured ablative composite assembly. The film adhesive is cured providing a portion of a hot gas valve suitable for use in tactical missiles. The film adhesive does not erode at the high temperatures (5000° F.) encountered in hot gas rocket exhausts, thereby providing a seal that offers high strength, pressure-tight joints.

摘要： Apparatus is disclosed for measuring creep stiffness of a specimen, for example, asphalt cement, or other viscoelastic material, having a flexural modulus greater than approximately 1,000 psi. The specimen and the lower part of a loading mechanism are submerged in a constant temperature coolant thereby providing buoyant support to the specimen, preventing it from deflecting under its own weight, as well as providing means for controlling the test temperature. The coolant temperature is maintained to within approximately +/-0.1.degree. C. of a desired temperature. The specimen, having known dimensions, is supported within the coolant on two spaced apart support members. A loading head actuated by an air bearing/pneumatic piston mechanism engages the specimen midway between the two support members. The deflection of the specimen is measured with an LVDT and the load imparted to the specimen by a load cell provided under at least one of the specimen support members. In order to prevent the buildup of frost on the apparatus, those components which extend from the air into the coolant are composed of low conductive material such as polymethylmethacrylate.

摘要： An active user interface system includes a gimbal assembly that is configured as a dual-input/single-output differential mechanism. The differential mechanism implements a speed reduction from the inputs of the differential mechanism to the output of the differential mechanism. Speed reduction enables the maximum drive torque that is supplied to the user interface about one rotational axis to be greater than the maximum drive torque that is supplied to the user interface about another, perpendicular axis.
