WASHINGTON Uomo Supreme X Nike Air More Uptempo Suptempo Nere Italia , Feb. 29 (Xinhua) -- U.S. space agency NASA on Monday took the first step towards the possible return of supersonic passenger air travel by awarding a 20-million-U.S.-dollar contract for the preliminary design of a "low boom" flight demonstration aircraft.



NASA Administrator Charles Bolden announced at an event at the Ronald Reagan Washington National Airport in Arlington, Virginia, that the agency has selected a team led by defense giant Lockheed Martin to complete the preliminary design for the Quiet Supersonic Technology (QueSST) aircraft within 17 months.


"We're here today to talk about NASA's work to make flight cleaner, greener, safer and quieter -- all while developing aircraft that travel faster -- and building an aviation system that operates more efficiently Uomo Supreme X Nike Air More Uptempo Scottie Pippen Bianche Nere Rosse Italia ," Bolden said at the event.

"And here's the magical part: the design is for a piloted test aircraft that can fly at supersonic speeds but create a sonic boom that's more like a soft thump instead of the annoying 'boom' that currently prohibits commercial supersonic flight over land," he said.

博尔登说,美国航天局的目标是在研发飞得更快的客机的同时,让飞机的系统更有效地运行,从而让飞行更加绿色、安全与安静。这款飞机被命名为“静音超音速技术”客机,其神奇之处在于,它能以超音速飞行,但在飞行速度突破音速时产生的音爆比较轻柔 Uomo Supreme X Nike Air More Uptempo Suptempo Rosse Bianche Italia ,而不是那种导致超音速飞行在陆地上空被禁止的恼人噪音。

The detailed design and building of the QueSST aircraft will fall under a future contract competition, the space agency said.

QueSST is part of NASA's 10-year New Aviation Horizons initiative, which "has the ambitious goals of reducing fuel use, emissions and noise through innovations in aircraft design that departs from the conventional tube-and-wing aircraft shape."

The New Aviation Horizons X-planes, according to NASA, will typically be about half-scale of a production aircraft and likely are to be piloted.

Design-and-build will take several years, with aircraft starting their flight campaign around 2020 depending on funding, it added.

“静音超音速技术”客机是美国航天局最近提出的“新航天地平线”计划的一部分。按照这项计划 Uomo Supreme X Nike Air More Uptempo Oro Italia ,美国航天局将在未来10年设计一系列X-飞机,这些示范型飞机将有着不同于传统飞机管状机身加一对机翼的外形,目标是降低燃油使用、排放以及噪音。

The first aircraft to break the speed of sound was the Bell X-1, a joint effort of the Bell Aircraft Corp., the U.S. Air Forces and the predecessor of today's NASA, known as the U.S. National Advisory Committee on Aeronautics.

Russia's Tupolev Tu-144 and the Concorde were the first supersonic civilian aircrafts to transport passengers at speeds greater than the speed of sound, but Tu-144 was retired in 1978 while the Concorde was retired in 2003 due to problems such as sonic booms.

历史上第一架突破音速的飞机是美国空军与美国航天局前身国家航空咨询委员会等联合研制的X-1。而曾经批量生产并投入商业运营的超音速客机仅有两种,分别是英国与法国联合研制的协和客机以及苏联的图-144 Uomo Off-Bianche x Air Jordan 1 The Ten Rosse Bianche Nere Italia ,但由于音爆等问题,图-144与协和客机分别于1978年和2003年退役。

The Panamanian lawyer at the center of a data leak scandal that has embarrassed a clutch of world leaders said on Tuesday his firm was a victim of a hack from outside the company, and has filed a complaint with state prosecutors.

Founding partner Ramon Fonseca said the firm, Mossack Fonseca, which specializes in setting up offshore companies, had broken no laws and that all its operations were legal. Nor had it ever destroyed any documents or helped anyone evade taxes or launder money, he added in an interview with Reuters.

Company emails Off White x Nike Vapormax Running Nere Bianche Italia , extracts of which were published in an investigation by the U.S.-based International Consortium of Investigative Journalists and other media organizations, were "taken out of context" and misinterpreted, he added.

"We rule out an inside job. This is not a leak. This is a hack," Fonseca, 63, said at the company's headquarters in Panama City's business district. "We have a theory and we are following it," he added, without elaborating.

"We have already made the relevant complaints to the Attorney General's office Off White x Nike Presto Virgil Abloh Nere Italia , and there is a government institution studying the issue," he added, flanked by two press advisers.

Governments across the world have begun investigating possible financial wrongdoing by the rich and powerful after the leak of more than 11.5 million documents, dubbed the "Panama Papers," from the law firm that span four decades.

The papers have revealed financial arrangements of prominent figures, including friends of Russian President Vladimir Putin, relatives of the prime ministers of Britain and Pakistan, and the president of Ukraine.

On Tuesday Off White x Nike Blazer Studio Mid The Ten Bianche Italia , Iceland's prime minister, Sigmundur David Gunnlaugsson, resigned, becoming the first casualty of the leak.

"The (emails) were taken out of context," Fonseca said.

He lamented what he called journalistic activism and sensationalism, extolling his own investigative research credentials as a published novelist in Panama.

"The only crime that has been proven is the hack," Fonseca said. "No one is talking about that. That is the story."

France announced on Tuesday it would put the Central American nation back on its blacklist of uncooperative tax jurisdictions.

Alvaro Aleman, chief of staff to President Juan Carlos Varela Off White x Nike Air Force 1 Low The Ten Bianche Italia , told a news conference the government could respond with similar measures against France, or any other country that followed France's lead.

WASHINGTON, Sept. 16 (Xinhua) -- The U.S. government has not changed its position on withdrawing from the Paris Agreement on climate change, the White House said on Saturday.

"As the President (Donald Trump) has made abundantly clear, the United States is withdrawing unless we can re-enter on terms that are more favorable to our country," the White House said in a statement.
