Patent number: 6616095Abstract: The subject tiltrotor aircraft has three modes of operation: airplane mode, helicopter mode, and transition mode. A tilting mast, which transitions the aircraft between airplane mode and helicopter mode, is controlled by systems that allow selective movement of the rotor blades between the flight modes. A hub couples the rotor blades to the tilting mast such that torque and thrust are transferred, while allowing rotor thrust vector tilting. A main swash plate controls rotor thrust vector direction. Pitch horns are coupled to the rotor blades and the main swash plate via pitch links such that swash plate inputs are communicated to the rotor blades. The pitch links are coupled at “delta-3” values that are not optimum. A feedback swash plate and feedback links receive disk tilting inputs from the rotor blades, and supply inputs to the main swash plate, which compensates for the less than optimum delta-3 coupling.Type: GrantFiled: January 18, 2002Date of Patent: September 9, 2003Assignee: Bell Helicopter Textron Inc.Inventors: Frank B. Stamps, James L. Braswell, Jr., David A. Popelka, Richard L. Bennett, Thomas B. Settle, Jr., Charles E. Covington, Cecil E. Covington

Patent number: 6585832Abstract: The present invention relates to an improved method for the manufacture of aircraft engine cylinder barrels to prevent their premature failure due to hairline cracks or specks thought to be caused by caustic stress corrosion cracking during black oxide treatment. Machined aircraft cylinder barrels immersed into a black oxide chemical bath composed of a solution containing about 60% sodium hydroxide, about 0% sodium nitrate, and about 40% sodium nitrite most effectively prevents specks and hairline cracks. Since residual stresses from machining also contribute to the probability that specks or hairline cracks will occur during black oxide treatment, the maximum selected number of cylinder barrels essentially free of detectible specks or hairline cracks determines the maximum number of cylinder barrels to be machined on a given set of tool bits.Type: GrantFiled: May 9, 2001Date of Patent: July 1, 2003Assignee: Textron LimitedInventor: Yoon Sam Kim
