20210010373 | HYDRAULIC SUPPORT MONITORING SUPPORT POSE IN REAL TIME BASED ON INERTIA MEASUREMENT UNIT AND DETECTION METHOD THEREOF - A hydraulic support monitoring a support pose in real time based on an inertia measurement unit (IMU) and a detection method thereof. In the hydraulic support, IMU sensors are separately mounted on a roof beam, a rear linkage, and a base, and an auxiliary support pose monitoring system is disposed. Each IMU sensor measures movement states of the roof beam, the rear linkage, and the base of the support in real time, and the support pose monitoring system processes the movement states to monitor a support pose of the hydraulic support in real time. Especially, it can be technically determined whether the hydraulic support is adequately lowered, moved or raised, thereby effectively reducing the labor intensity of workers and improving the working efficiency of the hydraulic support. | 2021-01-14 |
20210010374 | ROTARY ENGINE WITH RECIRCULATING ARC ROLLER POWER TRANSFER - The disclosure provides rotary machines that include, in one embodiment, a shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first gearbox disposed thereon defining one or more cavities therein. At least one contour is slidably received into an arcuate cavity in an exterior surface of the gearbox. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume. A gearbox mechanism consisting of gears, crankshafts, bearings and connecting rod creates an oscillatory motion 2 times per revolution such that the contour can navigate about the arcuate cavity without contacting the cavity at a high rate of rotating speed. Thus, said working volume can expand and compresses twice per rotatable shaft revolution. | 2021-01-14 |
20210010375 | MISTUNING OF TURBINE BLADES WITH ONE OR MORE INTERNAL CAVITIES - A bladed rotor system includes first and second sets of blades with respective airfoils each having at least one internal cavity. The airfoils of both the first and second sets of blades have identical outer shapes defined by an outer surface of an outer wall of the respective airfoils. The airfoils of the first set of blades are distinguished from the airfoils of the second set of blades by a geometry and/or position of at the least one internal cavity, which is unique to blades of a given set. The natural frequency of a blade of the first set differs from the natural frequency of a blade of the second set by a predetermined amount. The blades of the first set and the second set are alternately arranged in a periodic fashion in said circumferential row, to provide a frequency mistuning to stabilize flutter of the blades. | 2021-01-14 |
20210010376 | FLUID COOLING SYSTEMS FOR A GAS TURBINE ENGINE - A heat exchanger includes an airfoil configured to be positioned in a coolant stream. The airfoil includes a pressure sidewall and a suction sidewall coupled to the pressure sidewall. The suction sidewall and the pressure sidewall define a leading edge and a trailing edge opposite the leading edge. The leading edge defines an impingement zone wherein the coolant stream is configured to impinge the airfoil. The heat exchanger also includes at least one channel defined within the airfoil between the pressure sidewall and the suction sidewall. The at least one channel is at least partially defined within the impingement zone proximate the leading edge. | 2021-01-14 |
