The transonic speed range is that range of speeds within which the airflow over different parts of an aircraft is between subsonic and supersonic. So the regime of flight from Mcrit up to Mach 1.3 is called the transonic range. [citation needed] Northrop X-4 Bantam (Mach 0.9) — Supersonic [1.2–5)
It is commonly accepted that the supersonic speed range starts at a free stream speed greater than Mach 1.3. Aircraft designed to fly at supersonic speeds show large differences in their aerodynamic design because of the radical differences in the behavior of flows above Mach 1. Sharp edges, thin aerofoil sections, and all-moving tailplane ...
Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level , this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h).
The vehicle design was intended to have about 20,000 kilometres (11,000 nautical miles) range and good subsonic and supersonic speed fuel efficiency, thus avoiding the problems inherent in earlier supersonic aircraft. The top speed is projected to be Mach 5+.
A hypersonic weapon is a weapon capable of travelling at hypersonic speed, defined as above Mach 5, or above 5 times the speed of sound. [1] Below Mach 1, weapons would be characterized as subsonic, and above Mach 1, as supersonic. Typical Low Earth Orbit atmospheric re-entry speed is Mach 25. [2]
The first full-scale supersonic passenger jet is expected to perform its maiden flight in 2027, according to the South China Morning Post, who first reported the test flight.
Quarterhorse, the Air Force's next hypersonic aircraft, has taken an epic leap. The SR-71 Blackbird successor is a step closer to breaking the airspeed record.
Concorde (which first flew in 1969) used variable geometry wedge-shaped intakes to achieve a maximum speed of Mach 2.2. A similar design was used on the F-14 Tomcat (the F-14D was first delivered in 1994) and achieved a maximum speed of Mach 2.34. Many supersonic aircraft wings are designed around a thin diamond shape.
