A hybrid electric aircraft is an aircraft with a hybrid electric powertrain. It typically takes off and lands under clean and quiet electric power, and cruises under conventional piston or jet engine power. This makes long flights practical, while reducing their carbon footprint. [115]
An electric vertical take-off and landing (eVTOL) aircraft is a variety of VTOL (vertical take-off and landing) aircraft that uses electric power to hover, take off, and land vertically.
The EMALS uses a linear induction motor (LIM), which uses alternating current (AC) to generate magnetic fields that propel a carriage along a track to launch the aircraft. [5] [6] The EMALS consists of four main elements: [7] The linear induction motor consists of a row of stator coils with the same function as the circular stator coils in a conventional induction motor.
Battery-powered electric planes could be the future of aviation. Pipistrel, Ampaire, Eviation, and MagniX are betting on zero-emissions air travel. Why electric planes haven't taken off yet

The term elephant walk dates to World War II when large fleets of allied bombers would conduct attacks in missions containing 1,000 aircraft. Those who observed the taxiing of these large numbers of aircraft to take off in single file in nose-to-tail formations said that they looked like elephants walking to the next watering hole.
By July 1948 their proposal incorporated the stacked engine configuration and a high-mounted tailplane. Designed for Mach 1.5, the wing leading edge was swept back 40° to keep it clear of the Mach cone. [11] This proposal was submitted in November 1948, [12] and in January 1949 the project was designated P.1 by English Electric.
A human-powered aircraft (HPA) is an aircraft belonging to the class of vehicles known as human-powered transport.. As its name suggests, HPAs have the pilot not only steer, but power the aircraft (usually propeller-driven) by means of a system similar to a bicycle or tricycle: a pair of pedals, moved by the pilot's feet that turns a gear, which then moves a bicycle chain, which then rotates a ...
