The FAA is the third aviation authority to give its stamp of approval for the PW812D engine, after Transport Canada and the European Union Aviation Safety Agency.
Since Embraer announced its Energia concepts last year it has been busy evaluating different architectures and propulsion systems. These efforts have resulted in the updates of its concepts for 19-30 seat designs.
H3 Dynamics' 25kg test aircraft has electric flight range of up to 900km on liquid hydrogen, or 350km with pressurised hydrogen. Its externalised nacelle design also frees up 30 litres of fuselage volume.
Following analysis of this early concept ground test, the partnership plans a series of further rig tests leading up to a full-scale ground test of a Rolls-Royce Pearl 15 jet engine.
A new project will combine two innovative technologies - Water-Enhanced Turbofan and hybrid-electric propulsion - with Pratt & Whitney's GTFTM engine architecture.
A new Active Taping Kit tool enables a robot to use varying pressure when applying tape to an aircraft. It allows for smooth masking on parts varying in shape and puts down perfectly straight tape lines.
Ground and flight testing this fuel cell engine architecture should begin onboard the ZEROe demonstrator aircraft towards the middle of the decade. The A380 is currently being modified to carry liquid hydrogen tanks.
The agreement will look for the best pathways to move from current cell chemistries (advanced lithium-ion) to all solid-state designs which could double the energy density of batteries in the 2030 timeframe.
The hybrid-electric aircraft preserves the range/payload capability of the Grand Caravan, and in fact can fly farther than the Grand Caravan with eight passengers. Maximum range is beyond 1,000 miles.
A new multi-year agreement with BJG will allow KAI to minimise inventory and assure consistent quality supply as program requirements dictate.
Sled testing allows engineers to reproduce the dynamic conditions of a full-scale crash event in a controlled environment. The reverse accelerator sled being installed can produce up to 100g accelerations.
The 100,000 square-foot facility will initially house research and development of laser metal deposition with wire (LMD-w) additive manufacturing technology for large-scale titanium aerostructures.
With mode transition successfully demonstrated, the Hermeus team is now racing to manufacture the first Quarterhorse aircraft that will begin flight testing in late 2023.
Rolls-Royce says testing ALECSys low-emissions technology in flight will allow the verification of altitude operability performance and provides experience of operating a lean-burn system ahead of entry into service.
Summit Aviation's new location in Greensboro hosts machinery including a new 4 x 12-foot 5-axis mill. It will allow technicians to machine landing gear, leading edges and wing spars up to 12 feet long.
The GKN team has demonstrated fuelling and storage of liquid hydrogen, conditioning and distribution of cryogenic gas, and the use of PEM fuel cells to generate electrical power.
