Pipistrel tests hybrid electric; Russia flies tiltrotor UAV; coatings for smoother flying; Airbus in Singapore delivery-UAV trial; structure says where it hurts.
From battery weight and cost to motor cooling and electric arcing, a long list of issues must be tackled to make electric propulsion a reality for large aircraft.
Rolls-Royce Liberty Works and United Technologies Research Center are assessing whether parallel hybrid turbine-electric propulsion could provide fuel and emissions savings in otherwise conventional single-aisle airliners.
The new SS2 will begin captive carriage flight tests beneath the company’s WhiteKnightTwo carrier aircraft later this year, leading to glide flights and later powered flights using the new motor.
Even though the GAO has sided with the Air Force and its incumbent bomber provider, a contentious atmosphere means we have probably not heard the end of this dispute.
Airliners, without any new equipage, will soon fly as if in domestic airspace over oceans and remote areas using Aireon’s satellite-based surveillance network, unless routes cross into regions that have not signed up.
A small cadre of designers are boosting safe and efficient access to airports around the globe for the growing number of aircraft that have performance-based navigation capability.
California-based nonprofit R&D organization Aerospace Corp. sees it role as becoming fluent in counter-UAS technologies so it can advise its government clients on their effectiveness.
The radar for the GlobalEye is already running, in rooftop tests at Saab’s Gothenburg site, and the first Global 6000 platform for the UAE is due to arrive in Linkoping soon for modifications.
Saab is proposing a maritime patrol aircraft based on the Bombardier Global 6000 business jet that it regards as a competitor to Boeing’s P-8 Poseidon, at perhaps two-thirds the price.
Experts back idea of carrier-based refueling UAV; McCain presses Obama to stand up to China; U.S. Air Force still working cost growth on GPS ground segment; airlines can apply for flights to Cuba.
After evaluating clean-sheet designs for the U.S. Air Force’s T-X trainer requirement, Lockheed Martin decides to stick with Korea Aerospace Industries’ T-50.
General aviation boosters are extremely wary of the proposed Aviation Innovation, Reform, and Reauthorization (AIRR) Act, fearing airline control if it is passed into law.
On the sidelines of this week's air show, Aviation Week editors discuss whether Airbus really has the edge over Boeing it claims, and what defense hardware is in high demand in the Asia Pacific region.
The initial payloads on the first launch of the heavy-lift Space Launch System will be relatively small CubeSats, but the results could be huge, heralding a day when swarms of minuscule satellites ride piggyback deep into the Solar System for missions now conducted by billion-dollar, custom-built spacecraft.
The U.S. Air Force will need help from Congress to pursue its next-generation launch system plan, but Sen. John McCain (R-Ariz.) continues pressure against the use of RussianRD-180 rocket engines.
