Publication number: 20220363376Abstract: An improved aircraft design to harness advantages of vertical or short-takeoff and landings (V/STOL) and efficient horizontal flight. Configuration improves aircraft flight stability and efficiency in flight profiles: (1.) vertical flight; (2.) transition to and from horizontal flight and; (3.) horizontal flight on wings. The aircraft is capable of stable flight at any airspeed from hover to its maximum designed speed. It has the possibility of a controlled emergency landing using autorotation or, wings or, a combination of the two. Aircraft design includes: multiple thrust sources and, wings free to rotate on a spanwise axis. Wing rotation is independent—not coupled—with either the fuselage or, the thrust sources. Wing configurations include single, tandem or, multiple sets. Wings are coupled each other such that rotation induced in one wing affects rotation in all wings. Thrust sources are directed vertically during hover and some degree forward of vertical for horizontal flight.Type: ApplicationFiled: March 31, 2022Publication date: November 17, 2022Applicant: Autonomous Flight Systems Inc.Inventor: Edward Dolejsi

Patent number: 9821863Abstract: A bluff body adaptive wake reduction system includes a series of fairings mounted to outer surfaces of the aft end of the road vehicle. The fairings are streamlined in geometry with an outer surface, a partially hollow core, and with a rear end surface curved such that left and right hand sides are convergent behind the vehicle. The fairings are coupled to at least one ram air inlet and also include at least one blown slot positioned on the rear end of the fairings enabling air flow to exit the fairings tangent to the rear end surface of the fairings. Air flow enters the system through the ram air inlets and exits through the blown slots. Air flow exiting the blown slots promotes flow traveling over the outer surface to remain attached to the outer surface and thus to the rear end surface. The rear end surface then deflects air flow to follow a convergent trajectory behind the vehicle in such a fashion as to reduce the size of the wake, and as a result reduce the aerodynamic drag.Type: GrantFiled: September 20, 2016Date of Patent: November 21, 2017Assignee: American Dynamics Flight Systems, Inc.Inventor: Paul Vasilescu

Patent number: 6375381Abstract: A joint assembly is provide between a machine element gear and a shaft or between two shafts. The joint is brought about by forming a predetermined configured surface on the exterior of the machine element and forming a similar configuration of the same general dimensions on a raised surface on the shaft. The shaft is initially inserted into the machine element in a light force fit so that the similar predetermined configurations on the machine element and the raised surface of the shaft are in alignment. A metal cylindrical torque ring is positioned over and surrounding the two mating and abutting predetermined surfaces. By the process of magneforming, the cylindrical torque ring is deformed inwardly to be tightly pressed against the predetermined surfaces, thereby spanning the exterior of those surfaces and providing a tight joint between the machine element and the shaft.Type: GrantFiled: January 6, 2000Date of Patent: April 23, 2002Assignee: Curtiss Wright Flight Systems, Inc.Inventors: Gary Steven Ruschke, Desi J.
