What fuel do supersonic planes use?

Turbine Fuel, Low Volatility, JP-7, commonly known as JP-7 (referred to as Jet Propellant 7 prior to MIL-DTL-38219) is a specialized type of jet fuel developed for the United States Air Force (USAF) for use in its supersonic military aircraft; including the SR-71 Blackbird and the Boeing X-51 Waverider.

What fuel do private jets use?

Jet fuel is a colorless kerosene-based fuel and is generally used for jet engines and turboprops. The second type of fuel is called aviation gas or AVGAS. This is used for small piston-engine planes and propeller aircraft. More often than not, these are used by some of the best private jet companies.

What fuel does the u2 use?

Jet
Fuel. The U-2 has used Jet Propellant Thermally Stable (JPTS) since the aircraft’s development in the 1950s.

Do supersonic jets use more fuel?

Supersonic aircraft are estimated to burn five to seven times as much fuel per passenger as a regular aircraft, according to the nonprofit International Council on Clean Transportation.

What kind of fuel does the Blackbird use?

Jet Propellant 7
But the SR-71 is finicky, demanding fuel three times as expensive as the type used in airliners. The Blackbird uses a vintage 1970 military specification called MIL-T 38219, or Jet Propellant 7 (“JP-7” to its friends).

How many types of jet fuel are there?

two
There are two main types of jet fuel – Jet A and Jet A1. Although flight operators can use both fuels interchangeably for flight operations, there are some differences in manufacturing specifications.

What are the different types of jet fuel?

A basic distinction is made between four different aviation fuels:

  • Jet fuel (Jet A-1, kerosene)
  • Kerosene-gasoline mixture (Jet B)
  • Aviation gasoline (avgas)
  • Biokerosene.

Can the U-2 air refuel?

The U-2 is powered by a lightweight , fuel efficient General Electric F118-101 engine, which negates the need for air refueling on long duration missions.

Who makes JPTS fuel?

oil refineries
JPTS is a specialty fuel used only by the U-2 and is produced by two oil refineries in the United States. As such, it has limited worldwide availability and costs over three times the per-gallon price of the Air Forces primary jet fuel, JP-8.

How fast is supersonic in mph?

768 mph
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).

Is supersonic flight efficient?

Supersonic aircraft must have considerably more power than subsonic aircraft require to overcome this wave drag, and although cruising performance above transonic speed is more efficient, it is still less efficient than flying subsonically.
