Aviation fuelsare petroleum-based fuels, or petroleum and synthetic fuel blends, used to power aircraft. They have more stringent requirements than fuels used for ground use, such as heatingand road transport, and contain additives to enhance or maintain properties important to fuel performance or handling.
The Bell Boeing V-22 Osprey is an American multi-mission, tiltrotor military aircraft with both vertical takeoff and landing ( VTOL) and short takeoff and landing ( STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.
Fuel economy in aircraft. Between 1950 and 2018, efficiency per passenger grew from 0.4 to 8.2 RPK per kg of CO₂. [1] The fuel economy in aircraft is the measure of the transport energy efficiency of aircraft . Fuel efficiency is increased with better aerodynamics and by reducing weight, and with improved engine brake-specific fuel ...
An airship flies because the upward force, from air displacement, is equal to or greater than the force of gravity. Humans have managed to construct lighter-than-air vehicles that raise off the ground and fly, due to their buoyancy in the air. An aerostat is a system that remains aloft primarily through the use of buoyancy to give an aircraft ...
The 2006 transatlantic aircraft plot was a terrorist plot to detonate liquid explosives, carried aboard airliners travelling from the United Kingdom to the United States and Canada, disguised as soft drinks. [1] The plot was discovered by British Metropolitan police during an extensive surveillance operation.
Ground deicing of aircraft. In aviation, ground deicing of aircraft is the process of removing surface frost, ice or frozen contaminants on aircraft surfaces before an aircraft takes off. This prevents even a small amount of surface frost or ice on aircraft surfaces from severely impacting flight performance. Frozen contaminants on surfaces can ...
The frequency range in insects with synchronous flight muscles typically is 5 to 200 hertz (Hz). In those with asynchronous flight muscles, wing beat frequency may exceed 1000 Hz. When the insect is hovering, the two strokes take the same amount of time. A slower downstroke, however, provides thrust.
How you can plan ahead The safest bet is to take the first flight of the morning. That’s when temperatures are typically lowest, and also the least likely time of day for airlines to experience ...
