WebbThe NASA helicopter Ingenuity on Mars made the first powered controlled flights by an aircraft on a planet other than Earth. Its first flight was April 19, 2024, after landing February 18 attached to the underside of the Perseverance rover. Ingenuity weighs 1.8 kilograms (4.0 lb) and is 49 cm (19 in) tall. It is powered by six lithium-ion solar-charged … WebbRetreating blade stall is a hazardous flight condition in helicopters and other rotary wing aircraft, where the retreating rotor blade has a lower relative blade speed, combined with an increased angle of attack, causing a stall and loss of lift. Retreating blade stall is the primary limiting factor of a helicopter's never exceed speed, V NE. [1]
