Ampaire
Ampaire is an American aircraft manufacturer startup based in Hawthorne, California. History The company developed the Electric EEL, based on a Cessna 337 Skymaster (a push-pull aircraft) with a piston engine replaced by an electric motor powered by a battery, in a parallel hybrid configuration. The demonstrator first flew on 6 June 2019. In 2020, Scottish regional carrier Loganair trialled the Electric EEL with 70% fuel savings for short hops and 50% for longer flights of 50-250 miles (80-400 km). In February 2021, online booking platform Surf Air Mobility attempted to acquire Ampaire, but this was abandoned by April 2022. By then, ground tests of its ''Eco Caravan'', a hybrid-electric Grand Caravan, were under way, towards a first flight in the second half of 2022 and service entry in 2024, as a retrofit with a STC. The parallel hybrid architecture does not require recharging after each flight, to avoid being dependent on charging infrastructure. Ampaire is considering ...

Hybrid Electric Aircraft
A hybrid electric aircraft is an aircraft with a Hybrid electric vehicle, hybrid electric powertrain. As the energy density of lithium-ion batteries is much lower than aviation fuel, a hybrid electric powertrain may effectively increase flight range compared to pure electric aircraft. By May 2018, there were over 30 hybrid electric aircraft projects, and short-haul hybrid-electric airliners were envisioned from 2032. History The Boeing Truss-Braced Wing subsonic concept was planned with hybrid electric propulsion. The Diamond DA36 E-Star first flew on 8 June 2011, the first flight of a series hybrid powertrain, reducing fuel consumption and emissions by up to 25%, a technology scalable to a 100-seater airliner. A small and lighter Austro Engine 40 hp (30 kW) Wankel engine generates the electricity, supplemented by EADS batteries for silent take off, feeding a Siemens 70 kW (94 hp) electric motor turning the propeller. The AgustaWestland Project Zero was inten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Aircraft
An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being electric battery, batteries. Most have electric motors driving propellers or turbines. Crewed flights in an electrically powered airship go back to the 19th century, and to 1917 for a tethered helicopter. Model aircraft#Electric power, Electrically powered model aircraft have been flown at least since 1957, preceding the small unmanned aerial vehicles (UAV) or drones used today. Small Unmanned aircraft system, UAS could be used for parcel deliveries, and larger ones for long-endurance applications: aerial imagery, surveillance, telecommunications. The first crewed free flight by an electrically powered aeroplane, the Militky MB-E1, MB-E1, was made in 1973, and most crewed electric aircraft today are still only e ...

Dash 8
The De Havilland Canada DHC-8, commonly known as the Dash 8, is a series of turboprop-powered regional airliners, introduced by de Havilland Canada (DHC) in 1984. DHC was bought by Boeing in 1986, then by Bombardier in 1992, then by Longview Aviation Capital in 2019; Longview revived the De Havilland Canada brand. Powered by two Pratt & Whitney Canada PW150s, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. The Dash 8 was offered in four sizes: the initial Series 100 (1984–2005), the more powerful Series 200 (1995–2009) with 37–40 seats, the Series 300 (1989–2009) with 50–56 seats, and Series 400 (1999–2022) with 68–90 seats.

Boundary-layer Ingestion
Boundary layer suction is a boundary layer control technique in which an air pump is used to extract the boundary layer at the wing or the inlet of an aircraft. Improving the air flow can reduce drag. Improvements in fuel efficiency have been estimated as high as 30%. The boundary layer The air molecules at the surface of a wing are effectively stationary (see the no-slip condition). If the flow is smooth, known as laminar flow, the velocity of the air increases steadily as measurements are taken further away from the surface. However the smooth flow is often disturbed by the boundary layer breaking away from the surface and creating a low pressure region immediately behind the airfoil (see flow separation). This low pressure region results in increased overall drag. Attempts have been made over the years to delay the onset of this flow separation by careful design and smooth surfaces. Use of suction As flow separation results from the velocity deficit that is characteristic of bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ducted Fan
In aeronautics, a ducted fan is a thrust-generating mechanical fan or Propeller (aeronautics), propeller mounted within a cylindrical wiktionary:duct, duct or shroud. Other terms include ducted propeller or shrouded propeller. When used in vertical takeoff and landing (VTOL) applications it is also known as a shrouded rotor.Kotwani, Kailash;Ducted Fan or Shrouded Rotor Aerodynamics and its Application in Miniature VTOL Aerial Vehicles, 2009. (retrieved 22 March 2022). Ducted fans are used for propulsion or direct lift in many types of vehicle including Airplane, airplanes, airships, hovercraft, and powered lift VTOL aircraft. The high-bypass turbofan engines used on many modern airliners is an example of a very successful and popular use of ducted fan design. The duct increases thrust (physics), thrust, in comparison to a similar-sized propeller in free air. Ducted fans are quieter, and offer good opportunities for thrust vectoring.
