Ancora su Aerion Supersonic ... che punta decisamente a Mach 4 ...
Aerion is taking the next step in its quest for a family of supersonic jets, revealing on Monday the initial details for its second aircraft - the 50-passenger, Mach 4-plus AS3.
Fuller details of the airliner companion to its AS2 Mach 1.4 business jet are anticipated later this year, Aerion said, but sketched out a goal of reaching near-hypersonic speeds and a 7,000-nm range for the AS3.
The aircraft is anticipated to fly before the end of the decade, the company projected, adding that it will build on the AS2 that is anticipated to be in service by then.

Da Mach 4 a Mach 0 ... :eeeeek:
Supersonic aircraft developer Aerion Corp. on May 21 confirmed that it is ceasing operations of its AS2 business jet program after years of development, citing difficulty in raising the capital needed to complete production.
Employees were told of the development the same day.
The $120 million, planned Mach 1.4 AS2, scheduled for initial production in 2023 and first flight in 2024, counts Boeing and Spirit Aerosystems as investors and has been in development by Reno, Nevada-based Aerion for a decade.
The company had plans to invest $300 million to build a final assembly facility in Melbourne, Florida, and in March landed a commitment from NetJets for up to 20 AS2s.

La scelta di United Airlines ...
United Airlines said Thursday that it has reached a so-called commercial agreement with Boom Supersonic to order 15 Overture supersonic jets “once Overture meets United's demanding safety, operating, and sustainability requirements.”
The agreement also specifies options on another 35 airplanes.
Boom plans to fly a demonstrator of its supersonic concept sometime this year as it looks toward a rollout of a full-scale example in 2025 and entry into service in 2029.
Powered by three General Electric J85-15 turbojets, the composite-bodied XB-1 will fly up to Mach 2.2 ahead of the planned introduction of the 65- to 88-seat Overture.
Boom staged an online rollout ceremony for its one-third-scale XB-1 demonstrator last October and in March announced a “strategic investment” from American Express Ventures.

Hermeus ... l'Air Force ha deciso di continuare ad investire ...

Immagine
The Air Force has made another investment in hypersonic aircraft, teaming up with venture capital firms to give a $60 million contract to startup Hermeus, which is looking to develop a jet that can travel at five times the speed of sound.
The deal, awarded July 30 and announced Aug. 5, is not the first time the Air Force has invested in Hermeus - a year ago, the service and the startup announced a contract worth $1.5 million to look into modifying the company’s still-in-development aircraft for the future Presidential and Executive Airlift fleet, most notably Air Force One.
Now, USAF is making a broader investment in Hermeus and looking into other potential uses for reusable hypersonic aircraft.

Russia ... si attende l'autorizzazione definitiva alla realizzazione del dimostratore tecnologico "Strizh" ...
Russia’s aerospace industry is delaying a full-scale launch of a second-generation supersonic transport aircraft (SST2) while intensifying efforts to work out key technologies needed to deliver on that ambition.
The change in course was confirmed in a high-level government meeting last month when President Vladimir Putin himself approved a proposal by state-backed companies to develop the new Strizh (Swift) supersonic technology demonstrator to be powered by Klimov RD-93MA turbofans (a no-afterburning derivative of the MiG-35 fighter engine).
With a takeoff weight of 16 tonnes (35,273 pounds), the Strizh would serve as a platform to evaluate a package of new technologies such as pro-bionic structural airframe design (instead of classic frames and ribs) and engineering advances on engine/airframe integration to deliver a lower noise footprint around airports.
Having completed wind-tunnel and hot-gas testing on scaled models, the industry now awaits a government response to its proposal to build the 125-foot-long vehicle able to accelerate to speeds of up to Mach 1.8.
If Kremlin funding materializes in a timely manner, construction and flight testing would take place between 2022 and 2026.

La ditta Exosonic ha ricevuto un contratto preliminare relativo alla realizzazione di un "concetto" per un UAS supersonico che potrebbe avere potenzialità sia nel campo militare che in quello civile ...
Los Angeles-based startup Exosonic will develop a concept for a purpose-built, supersonic unmanned aircraft system (UAS) under a 15-month, $750,000 U.S. Air Force contract, the company announced Oct. 12 (*).
If a follow-on contract is signed to launch development, the unnamed UAS could serve a military role in adversary air training as well as help Exosonic continue development of a low-boom supersonic transport for the commercial and defense markets.

La European Union Aviation Safety Agency (EASA) interviene sulle normative sui jet supersonici civili ...
EASA has undertaken two rulemaking actions to develop environmental safeguards for the new generation of business jets and airline supersonic transports (SSTs) that are expected to become operational in the late 2020s.
An EASA advance notice of proposed amendment (A-NPA) aims to ensure that certified landing and takeoff noise limits for SSTs correspond to existing EASA requirements for subsonic jet airplanes.
Initial requirements for CO2 limits for SSTs are also being proposed.
Currently, no ICAO standards or recommended practices exist for SST noise limits.
Comments on the A-NPA are due July 25.

Boom svela il nuovo look di "Overture" e la partnership con Northrop Grumman ...
Supersonic airliner developer Boom has unveiled the refined configuration of its Mach 1.7 Overture passenger design and, at the same time, announced a partnership with Northrop Grumman to study military versions.
The significantly revised Overture design is tailored to meet Boom’s 4,250-nm range, high-speed mission requirement with 65-80 passenger, while simultaneously meeting stringent International Civil Aviation Organization (ICAO) Chapter 14/FAA Stage 5 takeoff-and-landing noise limits.
Reminiscent of supersonic concepts studied by Boeing and McDonnell Douglas in the late 1980s under NASA’s High Speed Civil Transport project, the new design features a horizontal tail and four wing-mounted engines, replacing the trijet arrangement of the earlier concept.
By increasing the number of engines, Boom says the Overture will be capable of takeoff at derated thrust settings, helping reduce noise.
Mounted in individual nacelles, the nonafterburning engines are staggered along the trailing edge of a large delta wing, which replaces the slender ogive design of the previous Concorde-like iteration.
The new wing is gulled in profile and incorporates what appears to be a sharper trailing edge sweep angle inboard with a reduced sweep outboard.
The revised wing is designed to provide improved lateral stability as well as additional lift at subsonic conditions without compromising supersonic cruise performance - enabling transonic overland flight close to Mach 1 and long-range overwater flights at Mach 1.7.
The engine arrangement also reduces aerodynamic interference drag while providing space for high-lift trailing edge devices.
The aft location also complies with positioning rules for modern turbine rotor burst safety regulations and places the engines aft of the cabin pressure bulkhead.

Overture ... Rolls Royce si sgancia, a sorpresa, dal programma ...
Although in mid-2020 Boom announced that Rolls-Royce signed an “engagement agreement” to explore the technical requirements for powering the Overture, the UK engine maker told AIN that it reached a decision not to further participate in the program.
“We’ve completed our contract with Boom and delivered various engineering studies for their Overture supersonic program,” Rolls-Royce said in a statement.
“After careful consideration, Rolls-Royce has determined that the commercial aviation supersonic market is not currently a priority for us and, therefore, will not pursue further work on the program at this time. It has been a pleasure to work with the Boom team and we wish them every success in the future.”
