Convair CV-240 familyThe Convair CV-240 is an American airliner that Convair manufactured from 1947 to 1954, initially as a possible replacement for the ubiquitous Douglas DC-3. Featuring a more modern design with cabin pressurization, the 240 series made some inroads as a commercial airliner, and had a long development cycle that produced various civil and military variants. Though reduced in numbers by attrition, various forms of the "Convairliners" continue to fly in the 21st century.
Hybrid electric aircraftA hybrid electric aircraft is an aircraft with a 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. The Boeing Truss-Braced Wing subsonic concept was planned with hybrid electric propulsion.
Dornier 328The Dornier 328 is a turboprop-powered commuter airliner. Initially produced by Dornier Luftfahrt GmbH, the firm was acquired in 1996 by Fairchild Aircraft. The resulting firm, named Fairchild-Dornier, manufactured the 328 family in Oberpfaffenhofen, Germany, conducted sales from San Antonio, Texas, United States, and supported the product line from both locations. A jet-powered version of the aircraft, the Fairchild Dornier 328JET, was also produced. The Dornier 328 program was initially started while Dornier was still owned by Deutsche Aerospace.
