By Allison Lampert MONTREAL (Reuters) - A new generation of U.S.-produced commercial supersonic jets must be no louder than existing planes or risk exacerbating existing complaints over noise from air traffic, Angela Gittens, director of Airports Council International (ACI) said. U.S. supersonic jet makers are working to reintroduce ultra-fast passenger planes for the first time since the Anglo-French Concorde retired in 2003, with the U.S. Federal Aviation Administration (FAA) working on proposed rules for noise certification of supersonic aircraft by 2020. These latest supersonic jets, while quieter and more fuel efficient than the Concorde, have difficulty meeting existing noise levels and carbon emissions standards for conventional planes due to engine constraints and higher fuel burn. Gittens told Reuters in an interview late on Monday that supersonic jets should not get "a free pass" to generate more noise than subsonic planes or fail to meet global carbon emission standards for … [Read more...] about Supersonic jets must be no noisier than existing planes
By Allison Lampert NEW YORK (Reuters) - Supersonic jet developer Aerion Corp is designing its first plane to run completely on biofuels to reduce emissions, even as the company calls for new global standards for planes that can conquer the sound barrier, the company's chief executive said on Thursday. Aerion's business jet AS2, with a $120 million (£92 million) list price per jet, would be capable of running on synthetic paraffinic kerosene (SPK) biofuel, CEO Tom Vice said at a Wings Club event in New York. Existing subsonic aircraft use a blend of biofuels and conventional jet kerosene to ensure the quality of the fuel does not harm the engine. Aerion's plane would have an engine designed with seals that could handle the biofuel, he said. "We believe that running biofuels will reduce our CO2 emissions by at least 40 percent," Vice said. Aerion and fellow supersonic plane makers Spike Aerospace and Boom Supersonic are working to reintroduce ultra-fast passenger planes for the … [Read more...] about Aerion designing supersonic jet to run completely on biofuels
News / UK and world by Press Association March 1, 2019, 2:46 am Send us a story Sign up to our Daily newsletter Concorde remains the world’s only supersonic airliner despite being grounded since October 2003. No government or manufacturer has since been able to build a commercial plane which can travel faster than the speed of sound. Many of the reasons for the demise of Concorde, high fuel costs, concern over its noise, a preference for lower fares over speed, are still applicable today, but that is not stopping a number of firms developing a supersonic airliner. Aviation analyst John Strickland does not believe another large scale version will be developed in the current market. He said passengers want to reach their destination as quickly as possible but paying the lowest fare is the priority for most people. “If you cut the time it takes to fly to Australia in half, there would be a level of interest,” he told the Press Association. … [Read more...] about What is the future for supersonic flight?
(Reuters) - Boeing Co said on Tuesday it had made a significant investment in Aerion, a developer of supersonic planes, as the world's biggest planemaker looks to tap into rising demand for high-end business jets that can cut travel time. The company will provide engineering, manufacturing and flight testing services for Aerion's $120 million supersonic business jet, Boeing said in a statement. The jet, Aerion AS2, slated for its first flight in 2023, can fly at speeds of up to Mach 1.4, or about 1,000 miles per hour, 70 percent faster than conventional business jets. Both, Boeing and Reno, Nevada-based Aerion did not disclose the financial terms of the deal. U.S. startups Aerion, Boom Supersonic and Spike Aerospace are working to re-introduce supersonic passenger travel for the first time since Anglo-French Concorde retired in 2003. Until now, supersonic designs have struggled to meet current subsonic noise standards due to engine constraints, but Aerion said in October it would be … [Read more...] about Boeing makes ‘significant investment’ in supersonic jet developer Aerion
Lockheed Martin's experimental supersonic plane has officially entered production, the defense giant announced Friday. Earlier this year, NASA awarded Lockheed a contract worth nearly $250 million to develop an aircraft capable of reaching supersonic speed without creating the deafening sonic boom that comes with breaking the sound barrier. Lockheed answered with its X-59 Quiet Supersonic Technology aircraft, which is designed to cruise at 55,000 feet and reach speeds of about 940 miles per hour. The new aircraft is expected to create a noise level akin to the sound of a car door closing. Current regulations ban commercial supersonic aircraft from operating over land. New companies like Boom Supersonic are trying to make use of the technology for transoceanic routes, with backing from investors like Richard Branson and Japan Airlines. But Lockheed Martin and NASA want to advance the technology through noise reduction to overturn regulations. The new experimental plane is designed to … [Read more...] about Lockheed Martin Starts Production of Its Experimental Supersonic Plane
