NASA’s Ingenuity Mars Helicopter Succeeds in Historic First Flight - Apr 19, 2021 [ IMAGE] NASA’s Ingenuity Mars Helicopter took this shot, capturing its own shadow, while hovering over the Martian surface on April 19, 2021, during the first instance of powered, controlled flight on another planet. It used its navigation camera, which ...
The Advancing Blade Concept system consisted of two rigid, contra-rotating rotors (30 inches apart) [9] which made use of the aerodynamic lift of the advancing blades. At high speeds, the retreating blades were offloaded, as most of the load was supported by the advancing blades of both rotors and the penalty due to stall of the retreating ...
A coaxial-rotor aircraft is an aircraft whose rotors are mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions (contra-rotating). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau.
Perseverance captured an image of Ingenuity on August 2, 2023, the day before the helicopter's 54th flight. - NASA/JPL-Caltech
NASA's extraterrestrial helicopter, Ingenuity, flew 40 feet into the Martian air and snapped an astonishing landscape on another world. On its 51st flight, the experimental craft — with rotors ...
Intermeshing twin rotors of a Kaman K-Max Video of K-Max helicopter in flight, showing the meshing main rotors in motion. Intermeshing rotors on a helicopter are a set of two rotors turning in opposite directions with each rotor mast mounted on the helicopter with a slight angle to the other so that the blades intermesh without colliding.
Sikorsky developed the X2 helicopter on a $50 million budget. The design includes expertise gathered from several earlier design projects. The S-69/XH-59A Advancing Blade Concept Demonstrator had shown that high speed was possible with a coaxial helicopter with auxiliary propulsion supplied using two jet engines, but that vibration and fuel consumption was excessive; [2] [3] [4] the Cypher UAV ...
Dissymmetry of lift in an American-style helicopter. Consider a single-rotor helicopter in still air. For a stationary (hovering) helicopter, whose blades of length of r metres are rotating at ω radians per second, the blade tip is moving at a speed rω meters per second. As the blades rotate, the speed of the blade-tips relative to the air ...
