rotor plane การใช้

• The accident raised new doubts about the future of the tilt-rotor plane.
• However up close near the rotor itself the air velocity is constant as it passes through the rotor plane.
• This causes the air passing through the rotor plane to have a smaller velocity than the free stream velocity.
• In 1939 Caldwell shut down Grey Goose and swapped shares once again, forming "'Rotor Planes, Inc . "'
• In 1935 H . Glauert derived the expression for turbine efficiency, when the angular component of velocity is taken into account, by applying an energy balance across the rotor plane.
• The Marine Corps grounded all MV-22 Osprey aircraft Tuesday following a crash in North Carolina that killed four Marines and raised new doubts about the future of the tilt-rotor plane.
• The U . S . Marine Corps grounded all MV-22 Osprey aircraft Tuesday after four Marines, died in a fiery North Carolina crash that reignited debate over the controversial tilt-rotor plane.
• Included are the most current new systems like the V-22 tilt-rotor plane and the F-22 fighter as well as upgrades to other planes, helicopters, ships and land vehicles.
• In Philadelphia on Monday, the widow of a Marine pilot killed in a V-22 crash last April urged Congress to ask tough questions before putting the tilt-rotor planes back in operation.
• The commandant of the Marine Corps grounded all MV-22 Osprey aircraft Tuesday following a crash in North Carolina that killed four Marines and raised new doubts about the future of the tilt-rotor plane.
• The Marine Corps grounded its fleet of Osprey aircraft Tuesday, hours after one of the craft crashed Monday in North Carolina, killing all four marines aboard and raising new questions about the tilt-rotor plane.
• The budget provides for several advanced aircraft, including the F-22 fighter, the V-22 tilt-rotor plane, a new amphibious assault vehicle and upgrades to helicopters and AV-8B and F / A-18 warplanes.
• The C . 8R incorporated drag hinges, due to blade flapping motion causing high blade root stresses in the rotor plane of rotation; this modification, however, resulted in other problems such as ground resonance for which drag hinge dampers were fitted.
• Raising new concerns about the future of the $ 40 billion Osprey aircraft program, a second fatal crash of the tilt-rotor plane prompted the Marine Corps Tuesday to ground its fleet and delay the critical decision on moving into full-scale production.
• These new revelations added to the concern of Pentagon supporters of the tilt-rotor plane, which takes off and lands like a helicopter but flies horizontally like an airplane, that it could be one of the first programs slashed by the incoming administration.
• In 1934 Caldwell moved again, this time to Washington, DC . In a filing with the Maryland Securities and Exchange Commission he described the company as working solely on a new type of autogyro, which he referred to as a " disk-rotor plane ".
• The source of HSI noise is the flow volume around the advancing blade tip, hence it cannot be captured by examining only the acoustic sources on the surface of the blade, HSI noise is typically directed in the rotor plane forward of the helicopter, like thickness noise.
