摘要： An improved variable pitch oarlock of a rowing shell, including a gate for securing an oar, which is adapted to swivel about a vertical pin of a rigger of the rowing shell. The improvement residing in the inclusion of horizontal pivot means adapted to vary the horizontal angular displacement of the gate as it swivels about the vertical pin. In operation, the pitch of the oar blade can be correspondingly varied and accurately determined during all phases of the rowing stroke. The horizontal pin also provides the mounting for force sensors; ensuring horizontal and/or vertical forces can be measured. Also claimed is a method of coaching or training rowing crew(s), utilizing the variable pitch oarlock as herein described, wherein force, angle and depth measurements are taken and analyzed.

摘要： One aspect is a structural fault estimation system for a rotor system. The structural fault estimation system includes a plurality of sensors operable to provide a plurality of measured rotor loads and motion of the rotor system. A rotor loads and motion estimator is operable to produce a plurality of estimated rotor loads and motion for the rotor system. A rotor fault estimator is operable to determine residual rotor loads and motion as a difference between the measured rotor loads and motion and the estimated rotor loads and motion, and estimate fault magnitudes for the rotor system using least squares relative to fault models and the residual rotor loads and motion. The structural fault estimation system can perform structural fault estimation in real-time on an aircraft while in operation.

摘要： In a method for determining the free field thrust of a gas turbine engine the gas turbine engine is attached to a movable support means in an enclosed gas turbine engine test facility, and is operated at a selected engine operating point. The thrust applied by the engine to the thrust cradle is measured via thrust measurement means. Calculations are performed to determine the gas turbine engine intake momentum drag generated by airflow into the gas turbine engine intake, the thrust cradle drag force generated by airflow past the moveable support means of the thrust cradle, the base drag generated as a result of accelerating nozzle ejector airflow, a pre-stream tube force related to turning of stream lines in the intake air path, a pre-stream tube force related to a bell mouth pull-off force. Also forces due to forward anemometer plane and nozzle static pressures and a nozzle exit buoyancy force and determined, and all of these forces are summed according to their respective positive and negative values to determine the free field thrust of the engine at the selected engine operating point.

摘要： PURPOSE:To accurately measure all propulsions in both high and low propulsion regions, by connecting a load cell to a rocket motor driving step. CONSTITUTION:When propelling powder of a rocket motor 4 is ignited, the motor 4 generates a repulsion in a direction A, and when a high propulsion is generated, force-making power of a tension spring 8 is overcome, and a compression load of nearly a kg is applied onto a load cell 3. And then, when the motor 4 generates a low propulsion, a tension load of nearly a kg is applied onto the load cell 3. And, a value, which is obtained by adding the force-making power P kg of the spring 8 to a value detected by the load cell 3, is to become an actual propulsion of the motor 4. And, the low propulsion is measured in the neighborhood of the bottom detection limit which is the most accurate section of the cell 3, and the high propulsion is measured in the neighborhood of the top detection limit which is the most accurate section of the cell 3.
