Symphony will be a conventional medium-bypass turbofan engine, but with a Boom-designed axisymmetric supersonic intake, a variable-geometry low-noise exhaust nozzle, and a passively cooled high-pressure turbine.
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.
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.
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.
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.
With the Falcon 10X, Dassault is taking a new approach to ground testing, which will be used to demonstrate the maturity of all systems well before the aircraft even takes to the air.
Engine certification will continue through the first half of 2023, including flights currently under way on the P&W flying test bed in Mirabel, as well as endurance testing to ensure product maturity at entry into service.
In order to provide the 4 MW of electrical power required for operations, the airship will incorporate a total of four 1 MW turbogenerators in the nacelles located in the side fins of the aircraft.
The PW127XT-M engine is reckoned to offer 40% extended time on wing, 20% lower maintenance costs and a three per cent improvement in fuel efficiency. It will also fly on 100% SAF.
The PT6 E-Series was chosen as a reliable and versatile turboprop engine family that will deliver the performance characteristics required as GA-ASI continues its development of MQ-9B capabilities.
The airframe has been re-engineered to reduce drag, with such changes as replacing the external pilot entry step with a foldable ladder, and adding flaptrack covers on the wing and wheel fairings to the landing gear.
Successfully demonstrated hybrid-electric technology could be implemented in a range of novel applications, including high speed eVTOL, unmanned aerial vehicles, and small to medium sized commercial aircraft.
With a fleet of over 1,000 engines, India's Armed Forces are one of the largest operators of Safran-designed helicopter engines. A new JV will further boost that number into the future.
The SAF used was 100% Hydroprocessed Esters and Fatty Acids Synthetic Paraffinic Kerosine (HEFA-SPK) acquired from World Energy. HEFA-SPK is a specific type of hydrotreated renewable feedstock fuel.
This milestone follows the flight of an H225 with one SAF-powered Makila 2 engine in November 2021, and is part of the flight campaign aimed at understanding the impact of SAF use on the helicopter's systems.
The first dedicated Pearl 10X test engine ran for the first time earlier this year and surpassed its target thrust levels on the first test run, making it the most powerful business aviation engine in the Rolls-Royce portfolio.
As main subcontractor for this major collaborative European programme, Airbus Defence and Space is responsible for the selection of the engine supplier - and was looking for performance combined with low risk.
