High-Speed AirCraft (Hisac), a European research program studying the feasibility of a supersonic business jet (SSBJ), is coming to a close at the end of this year. The research has shown better understanding of the performance such a vehicle could achieve, but it came to no conclusion about the types of engines that would be needed.
The design of new airframes always depends heavily on availability of new engine types. The very light jet segment, for example, had to wait until engine manufacturers Pratt & Whitney Canada and Williams International designed smaller engines to power a new class of light jet, and the same is true on the upper end of the market, with new large jets spurring development of ever more powerful and efficient turbofans.
For reasons that are not clear, every engine manufacturer scored fewer points in this year’s survey than in last year’s, something that did not happen with the airframers and avionics makers.
Brazil-based GP Aerospace is trying to raise $10 million to build a flying prototype of the company’s GP210 very light jet. The GP210 is a light twin-turbine VLJ powered by two 740-pound-thrust Price Induction DGen390 turbofans, which are currently under development. Performance targets for the four-seat twin are 4,300 pounds mtow, maximum altitude 25,000 feet and high-speed cruise of 276 knots.
GE Aviation will soon start certification testing of its new 800-shp H80 turboprop engine, derived from the Walter M601. Last summer, GE acquired certain assets of Prague, Czech Republic-based Walter Engines.
Rolls-Royce 250-series engine services provided by Essential Turbines of Dorval, Quebec, will now also be marketed by M7 Aerospace. Under the terms of the agreement, the company will service 250-series customers in the U.S. and in Central and South America. M7 will also market Essential Turbines’ overhaul services to federal, state and local government customers throughout the U.S.
GP Aerospace, a Brazilian startup company established by former Embraer technical director Guido Pessotti, has revealed to AIN plans for a personal very light jet, which would be smaller than currently available very light jets.

German-based engine manufacturer MTU Aero Engines is here at the Paris Air Show (Hall 2 Stand AB 151) exhibiting a cutaway mockup of a geared turbofan. This is the basic concept for its Claire (clean air engine) technology program, whose aim is to cut carbon dioxide (CO2) emissions by 30 percent by 2035. It is making its first step under the umbrella of the European Commission’s Clean Sky joint technology initiative.
Price Induction, a French startup company based in Anglet in the southwest of the country, is here exhibiting two engine mockups (Hall 3 Stand A25). The first is its new 570-pound-thrust DGEN 380 turbofan engine and the other is its Taor contrafan concept. Company executives claim to have raised enough funds to complete the DGEN certification program.
