It had a maximum speed over twice the speed of sound , at Mach 2. First flown in , Concorde entered service in and operated for 27 years. It is one of only two supersonic transports to have been operated commercially; the other is the Soviet-built Tupolev Tu , which operated in the late s.
The Progress D was an experimental aircraft engine, a hybrid between a turbofan and a turboprop known as a propfan. Also known as the Lotarev DT, the three-shaft geared engine was designed in the s and s to power proposed propfan aircraft such as the Tupolev Tu , Ilyushin Il, and Ilyushin Il Based on the core of the Ukrainian Progress D turbofan, the D was the first Soviet propfan, and as of it is still one of only four different unshrouded, contra-rotating propfan engines to have flown in service or in flight testing.
The Airbus A is a long-range , wide-body passenger jet airliner that was developed and produced by the European aerospace company Airbus. In the mids, Airbus conceived several derivatives of the A , its first airliner, and developed the A quadjet in parallel with the A twinjet. In June , Airbus launched both designs with their first orders and the A took its maiden flight on 25 October It was certified along with the A on 22 December and both versions entered service in March with launch customers Lufthansa and Air France. Both airliners have fly-by-wire controls, which was first introduced on the A , as well as a similar glass cockpit. The shortest A measured

Vanwege alle coronarestricties is het te onzeker of het door kan gaan, terwijl het evenement veel voorbereidingstijd kost. The Boeing Company today issued updates to its schedule of press activities at the Paris Air Show.
Aviation safety means the state of an aviation system or organization in which risks associated with aviation activities, related to, or in direct support of the operation of aircraft, are reduced and controlled to an acceptable level. It encompasses the theory, practice, investigation, and categorization of flight failures , and the prevention of such failures through regulation, education, and training. It can also be applied in the context of campaigns that inform the public as to the safety of air travel. Aviation safety should not be confused with aviation security which includes all of the measures taken to combat intentional malicious acts. For the ten-year period to , 0. From million passengers in , air transport had grown to 3, million in , led by million in the United States, then million in China. In , there were 10 fatal airliner accidents, resulting in 44 occupant fatalities and 35 persons on the ground: the safest year ever for commercial aviation, both by the number of fatal accidents as well as in fatalities.
The General Electric GE36 was an experimental aircraft engine , a hybrid between a turbofan and a turboprop , known as an unducted fan UDF or propfan. General Electric GE started performing studies and component test work on the concept that would become the UDF in , based on the initial results of early National Aeronautics and Space Administration NASA propfan technology studies that the aerospace agency first released to engine makers in Around the same time, GE was negotiating with Boeing, which felt that the UDF technology could be useful for short-haul airliners, to test a demonstration engine on a Boeing testbed aircraft. The engine would have a pair of six-stage contra-rotating free turbines , each with large diameters running at slow speeds, and they would be connected directly to a couple of eight-blade, foot diameter 3. GE unveiled a full-scale model of the engine at the Farnborough Air Show in September, promising a percent reduction in fuel consumption compared to current airliner engines without decreasing the cruise speed. Airlines also appreciated the UDF's lack of a gearbox , which transfers power from the turbine to the propeller while allowing both to run at their respective optimal rotational speeds , but was difficult to design reliably for high speed and power.
As of , it is still one of only four different contra-rotating propfan engines to have flown in service or in flight testing. Allison hoped to have its engine ready for flight tests in late PW—Allison Engines was to invest at least million dollars to bring the engine into commercial production depending on airline commitments to buy aircraft using its engines ,  and it assumed that the new company would take half of the market for new medium-sized airliners over the next ten years—a to billion dollar market, it estimated. On December 20, , Boeing and Allison agreed to test its new propfan engine for use on the Boeing 7J7. Although Boeing had not tested PW—Allison's propfan in flight, the airframer said that the PW—Allison engine's off-the-shelf core was not powerful enough to power the seat plane.

Он протягивал свою изуродованную руку… пытаясь что-то сообщить. Танкадо хотел спасти наш банк данных, - говорила она .
Мысли ее вернулись к Дэвиду. Сьюзен надеялась, что с ним все в порядке. Ей трудно было поверить, что он в Испании. Чем скорее будет найден ключ и все закончится, тем лучше для .
Он смотрел на приближающиеся огни центра города и молил Бога, чтобы он дал ему добраться туда живым. Беккер проехал уже половину пути, когда услышал сзади металлический скрежет, прижался к рулю и до отказа открыл дроссель. Раздался приглушенный звук выстрела. Мимо. Он резко свернул влево и запетлял по дороге в надежде сбить преследователя и выиграть время. Все было бесполезно.
