After the aircraft touched down, the right landing gear collapsed, the right wing hit the ground, and a fire broke out. The fire went out before the aircraft came to rest and all passengers and crew were evacuated. Five people had minor injuries, some from parts of the propeller entering the cabin and others from the evacuation. [citation needed]
Northwest Airlines Flight 292, a DC-7C (N285) with 7 crew and 95 passengers, [29] made a successful water landing in Sitka Sound just before 1 p.m. local time after struggling with propeller problems for 45 minutes [30] while operating as a military charter flight between McChord Air Force Base and Elmendorf Air Force Base. The plane stayed ...
The performance of a propeller suffers when transonic flow first appears on the tips of the blades. As the relative air speed at any section of a propeller is a vector sum of the aircraft speed and the tangential speed due to rotation, the flow over the blade tip will reach transonic speed well before the aircraft does.
Later advances included full-feathering and reversible propellers. Hamilton Standard was a division of United Aircraft Corporation (1934) along with Pratt & Whitney (engines). In the early 1950s Hamilton developed the technology to accurately meter fuel in jet engines, and its fuel controls were employed on Boeing 707s and Douglas DC-8s , as ...
Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races. Aircraft equipped with contra-rotating propellers (CRP) [1] coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra ...
The model was just 23-years-old when she walked into a plane's propeller in the dark, losing an eye, a hand and suffering brain damage. Because her tragic story made news headlines that night, the ...
A simple 3 blade toroidal propeller. A toroidal propeller is a type of propeller that is ring-shaped with each blade forming a closed loop. The propellers are significantly quieter at audible frequency ranges, between 20 Hz and 20 kHz, while generating comparable thrust to traditional propellers.
In designing the Lockheed P-38 Lightning, the decision was made to reverse the counter-rotation such that the tops of the propeller arcs move outwards (counterclockwise on the left and clockwise on the right), away from each other. Tests on the initial XP-38 prototype demonstrated greater accuracy in gunnery with the unusual configuration.
