As the era of the commercial hybrid airship dawns, we take a closer look at more features of the newly-launched Lockheed Martin LMH-1.

Engines in contention to replace Russia’s RD-180 on U.S. launches cover a lot of technology, from segmented solid propellant to the methane-burning Blue Origin BE-4.

The choice is effectively between market potential maximization and operating economics: A single-aisle jet offers lower production and operating costs but would miss much of the replacement market; a twin-aisle could stimulate new demand but would be more expensive to produce and operate.

The money, talent and business model could be found to break the Airbus and Boeing duopoly, but the vision may prove more elusive.

NASA researchers, together with the U.S. Air Force Research Laboratory (AFRL) are planning demonstrations of an autonomous unmanned aircraft system (UAS) capable of planning, launching, navigating and refueling itself.

A mission to count moose footprints is the first commercial unmanned-aircraft mission in Canada to be approved for beyond-visual-line-of-sight operation.

The extremely thin wing of the Transonic Truss-Braced Wing 4.5%-scale model meant the test team had to use pressure-sensitive paint, which can acquire data in areas inaccessible to conventional pressure measurements.
