Abstract: The subject mater herein relates to oil well testing and, more particularly, automated oil well test classification. Various embodiments described herein provide systems, methods, and software for statistical analysis and classification of oil well tests. Some embodiments include receiving a first set of oil well test results from one or more measurement devices of a well test separator, storing the first set of oil well test results in a database, and annotating one or more tests of the first set oil well test results. The annotated test results are then used to build one or more classification models to enable automated oil well test classification as new oil well tests are performed.

Abstract: A mount for suspending a laser medium has a cross section profile. The mount is configured to conduct heat away from the laser medium without imparting undue stress. The mount includes a laser host medium having a first cross section profile. A heat sink defines a bore. The bore has a second cross section profile configured to envelop the first cross section profile and further defines a generally uniform interspace between the first cross section profile and second first cross section profile. An amalgam of a mercury soluble metal is formed to substantially fill the interspace to support the laser host medium.

Abstract: A system for automatic multivariable calibration of an engine controller. The system may take inputs which include actuator setpoints, sensor measurements, performance requirements, and so forth. There may be an algorithm to compute engine calibration parameters for the controller. Each of the actuators may be separately stepped through to experimentally obtain actuator input and sensor output data. Algorithmic processing of the experimentally obtained data may be performed to calculate parameters of a model of an engine. A model based control design algorithm may then be invoked to obtain the calibration parameters for a controller. The calibrated controller may be tested with real or simulated engine conditions. The performance related to the parameters may be analyzed and determination of the acceptability of the data be made. If not acceptable, the parameters may be reprocessed. If acceptable, the calibration parameters may be downloaded to the engine controller for application and use.

Abstract: A sealing unit includes a mismatched metal-to-metal seal and an o-ring seal with a vent hole therebetween. The mismatched metal-to-metal seal may provide a sealing surface between two metals that may withstand high temperatures and pressure while avoiding leakage over many cycles. The sealing units of the present invention may provide a seal capable of withstanding pressures greater than about 5,000 psig, and typically greater than 6,000 psig, and more typically greater than 7,000 psig; and temperatures greater than about 300° F., and typically greater than about 400° F., and more typically greater than about 500° F. over a service life of more than 5,000 cycles. By providing a vent hole between the metal-to-metal seal and the o-ring seal, should either seal leak, damage to the other/good seal may be prevented by expelling the leak out of the system.

Abstract: A method and a system for measuring the velocity of a projectile. The method and system employ sensors that uses magnetoresistive sensing elements to measure the velocity of a projectile. Two magnetoresistive based sensors may be used to sense a time at which a projectile crosses a sense path associated with each of the sensors. Because the sensors employ magnetoresistive sensing elements, high quality voltage signals are produced, allowing accurate time measurements to be calculated. Accordingly, the velocity of the projectile can be determined by using these time measurements along with a measured spacing distance between the sensors.

Abstract: A cabin pressure control system (CPCS) software control logic modification may boost the voltage applied to a motor when conditions are sensed indicating a combination of larger than normal cabin pressure and cabin rate error conditions. The motor may be part of an open-loop system for operating a butterfly valve that may regulate outflow from the aircraft cabin. The larger than normal cabin pressure and cabin rate error conditions may be an indication that the outflow valve is not responding in a normal manner, potentially caused by excessive loading to the motor or motor degradation. By boosting the motor voltage during excessive load conditions or with a degraded motor, CPCS performance and robustness may be improved.

Abstract: The invention relates to a system of shaft sealing for a turbine engine. Carbon-ring seals placed on pressurized bearing compartments are adapted to operate on ceramic runners which are cooled by lubricating fluid. The runners are closed at one end so that fluid does not enter an interface between the runner and the seal. The seal is held in place in a cylindrical seal housing with an inwardly projecting seal retention wall. An internally cooled seal housing is provided having an enclosed annular cooling groove is formed in the wall. Fluid is circulated through the groove to provide cooling of the seal housing and the carbon-ring seal. The circulated fluid is provided from the same source as fluid that is circulated to lubricate bearings on the engine. However, a separately controlled fluid delivery system is employed so that a rate of flow of fluid to the seal housing can be specifically controlled.
