mach

Today, we don't talk about flying transonically, or even supersonically, we talk about flying hypersonically not Mach 2 or Mach 3, Mach 20.

Targets flying at up to Mach 2.5 can be successfully engaged or around Mach 8.5 for later models.

That's 18,000 miles an hour, just over Mach 23!

I've never seen a bird flying around at Mach 2.

Mach dir keine Sorgen, da ist kein Schnaps mehr übrig.

In 1947, there was no wind tunnel data beyond Mach 0.85.

You can't learn to fly at Mach 20 unless you fly.

The first Mirage IIIA flew in May 1958, and eventually was clocked at Mach 2.2, making it the first European aircraft to exceed Mach 2 in level flight.

The Mirage III attained a speed of Mach 1.8 in September 1957.

At the critical Mach number, local airflow in some areas near the airframe reaches the speed of sound, even though the aircraft itself has an airspeed lower than Mach 1.0.

The MiG 25's speed was limited to Mach 2.83 in operations, but it could reach a maximum speed of Mach 3.2 or more with the risk of damaging the engines beyond repair.

The phenomena associated with problems at the critical Mach number became known as compressibility.

Smaller shock angles are associated with higher upstream Mach numbers, and the special case where the shock wave is at 90 to the oncoming flow (Normal shock), is associated with a Mach number of one.

It is powered by the Volvo RM12, and has a top speed of Mach 2.

And in the second flight, three minutes of fully controlled, aerodynamic flight at Mach 20.

Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach 1).

At Mach 20, we can fly from New York to Long Beach in 11 minutes and 20 seconds.

In aircraft not designed to fly at or above the critical Mach number, shock waves in the flow over the wing and tailplane are sufficient to stall the wing, make control surfaces ineffective or lead to loss of control such as Mach tuck.

Its cruise speed will be Mach 0.785 and it will have a maximum altitude of 12,100 metres (39,800 feet).

The prototype Mirage III flew on 17 November 1956, and attained a speed of Mach 1.52 on its 10th flight.

Accelerating a spacecraft to orbital speed requires more than 60 times as much energy as accelerating it to Mach 3.

So that glider of yours, the Mach 20 glider, the first one, no control, it ended up in the Pacific I think somewhere.

Supersonic performances would have implied many difficulties of development, and it was decided to initially develop a relatively simple aircraft limited to Mach 0.95.

For example, if the MMO is Mach 0.83, then at where the speed of sound under standard conditions is , the true airspeed at MMO is .

Work then moved to the Royal Aircraft Establishment (RAE), where it continued as a research program into high speed (Mach 4 to 7) civilian airliners.

If a Mach 20 glider takes 11 minutes and 20 seconds to get from New York to Long Beach, a hummingbird would take, well, days.

Piloted by Gary Jennings, the aircraft reached a maximum speed of Mach 0.9 and an altitude of 40,000 feet (12,000 m) during the 75 minute flight.

It is thought that this design of engine could permit sufficient performance for antipodal flight at Mach 5, or even permit a single stage to orbit vehicle to be practical.

Staying under French radar coverage by flying low over the desert for more than 1,127 km (700 mi), it accelerated to over Mach 1, climbed to 5,030 m (16,503 ft) and dropped three heavy bombs.

He reached a top altitude of in the X 15 3, and a top speed of Mach 5.74 () in the X 15 1 he left the Dryden Flight Research Center with a total of 2,400 flying hours.

The vehicle design is for a hydrogen fuelled aircraft that would take off from a conventional runway, and accelerate to Mach 5.4 at altitude using the atmosphere's oxygen before switching the engines to use the internal liquid oxygen (LOX) supply to take it into orbit.
