Safran Uses A Historic Wind Tunnel For Testing A Novel Jet Engine Design
Safran, a French engine manufacturer, announced on Friday that wind tunnel testing for its "RISE" technology project, which involves designing radical jet engines for the upcoming medium-haul jets, has started.
The foundation for an open-bladed jet engine that can cut pollutants and fuel consumption by 20% starting in the middle of the following decade is being tested by Safran and its partner, GE Aerospace.
"RISE" is positioned as a potential replacement for the "LEAP" model, which is already in use on the Boeing 737 MAX and almost half of rival Airbus A320neo aircraft. In an effort to increase efficiency, "RISE" would have visible fan blades and double the diameter of current variants.
Since the front fan, which generates the majority of an engine's thrust, would not be placed inside the typical housing that is familiar to aeroplane passengers, a significant portion of the upcoming certification is anticipated to concentrate on the safe management of any blade failures.
A massive tunnel outside Modane in the French Alps houses a one-fifth prototype of the "Open Fan" concept that was unveiled to media on Friday. It will undergo 200 hours of testing.
Originally constructed in the Austrian Tirol, the historic S1MA wind tunnel was constructed using steel components and designs taken from a building site around the conclusion of World War Two. Nazi Germany had been racing to capitalise on breakthroughs in aviation and propulsion.
The designs called for an interchangeable system of 500-ton test chambers that fit into the enormous rectangular tunnel on rails and are still in use today.
The largest wind tunnel of its kind, according to France's ONERA research organisation, involves speeding air towards the sound barrier in order to equal or surpass normal cruising speeds.
The winding network of hillside tunnels, which uses only hydroelectric power—one-hundredth of France's total consumption—has tested legendary aircraft, including the Concorde, Airbus A380, and several generations of French fighters.
When subsidence was discovered ten years ago, its future was called into question, leading to an infusion of funding from Europe and France.
In terms of quantity sold, CFM is the biggest manufacturer of jet engines worldwide. It competes with Raytheon Technologies (RTX.N) as the only engine supplier for the Boeing 737 MAX and opens a new tab for Pratt & Whitney for airline engine selections on the Airbus A320neo.
