Transonic flow typically occurs in flows with Mach numbers between 0. 8 and 1. 2.

Transonic turbines operate at a higher pressure ratio than normal but are usually less efficient and uncommon.

The term Transonic refers to a range of velocities just below and above the local speed of sound ( generally taken as Mach 0. 8 – 1. 2 ).

The UD method was firstly introduced in 1995., and it was used extensively to measure flow and volumes with extracorporeal circuits condition such as ECMO and Hemodialysis, leading more than 150 peer reviewed publications, and now it has adapted to Intensive Care Units ( ICU ) settings as COstatus ( Transonic System Inc. Ithaca, NY ).

Transonic airspeeds see a rapid increase of drag from about Mach 0. 8, and it is the fuel costs of the drag that typically limits the airspeed.

Transonic speeds can also occur at the tips of rotor blades of helicopters and aircraft.

An intermediate step between Panel Codes and Full Potential codes were codes that used the Transonic Small Disturbance equations.

He has recorded albums as a bandleader, with David S. Ware, Matthew Shipp and others. Free jazz drummer Whit Dickey first stepped into the spotlight as a leader with the release of his Transonic album from Aum Fidelity in 1998.

Early the following year, the drummer began composing the works that would be included on Transonic.

Transonic buffeting effects had also been widely reported by pilots of propeller-driven Allied fighters including the Supermarine Spitfire, P-38 Lightning and P-51 Mustang, aircraft that were known to have top diving speeds of less than 0. 85 Mach.

He joined the Transonic Combustion, Inc. Board of Directors on May 24, 2010.

A problem is called subsonic if all the speeds in the problem are less than the speed of sound, transonic if speeds both below and above the speed of sound are present ( normally when the characteristic speed is approximately the speed of sound ), supersonic when the characteristic flow speed is greater than the speed of sound, and hypersonic when the flow speed is much greater than the speed of sound.

In aerodynamics, hypersonic speeds are speeds that are highly supersonic.

The hypersonic regime is a subset of the supersonic regime.

Thus jet engines, with a better match between speed and jet exhaust speed ( such as turbofans )— in spite of their worse )— dominate for subsonic and supersonic atmospheric use, while rockets work best at hypersonic speeds.

Air-breathing designs typically fly at supersonic or hypersonic speeds, and usually include a rocket engine for the final burn for orbit.

Whereas a flying wing seeks to maximize cruise efficiency at subsonic speeds by eliminating non-lifting surfaces, lifting bodies generally minimize the drag and structure of a wing for subsonic, supersonic, and hypersonic flight, or, spacecraft re-entry.

In aerodynamics, a hypersonic speed is one that is highly supersonic ( even though the origin of the words is the same --" super " is just the Latin version of the Greek " hyper ").

While the definition of hypersonic flow can be quite vague and is generally debatable ( especially due to the lack of discontinuity between supersonic and hypersonic flows ), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow.

Whereas a flying wing seeks to maximize cruise efficiency at subsonic speeds by eliminating non-lifting surfaces, lifting bodies generally minimize the drag and structure of a wing for subsonic, supersonic, and hypersonic flight, or, spacecraft re-entry.

The history of aviation has extended over more than two thousand years from the earliest attempts in kites and gliders to powered heavier-than-air, supersonic and hypersonic flight.

He is responsible for many key advances in aerodynamics, notably his work on supersonic and hypersonic airflow characterization.

A WaveRider is a hypersonic aircraft design that improves its supersonic lift-to-drag ratio by using the shock waves being generated by its own flight as a lifting surface, a phenomenon known as compression lift.

One of the many differences between supersonic and hypersonic flight concerns the interaction of the boundary layer and the shock waves generated from the nose of the aircraft.

Finally, for small perturbations in subsonic and supersonic flows ( not transonic or hypersonic ) these equations can be linearized to yield the linearized potential equations.

Other design projects ( not built ) included supersonic transport ( SST ) passenger aircraft, a mach-2 VTOL fighter, hovercraft, a jet engine-powered tank, and the hypersonic Space Threshold Vehicle.

' It dropped a large number of supersonic test vehicles, ranging from the X-15 to its last research program, the hypersonic X-43A, powered by a Pegasus rocket.

As the air enters the engine at supersonic / hypersonic speeds, it becomes very hot due to compression effects.

This can lead to dramatic improvements in lift for supersonic / hypersonic aircraft, which often fly at high altitudes and thus suffer from decreased lift due to the thin air.

Aerodynamic heating is a concern for supersonic and hypersonic aircraft.

The aerodynamic conditions required for flutter vary with the structure's external design and flexibility, but can range from very low velocities to supersonic flows.

In supersonic flows, expansion is achieved through an expansion fan.

In two and three dimensional supersonic flows, oblique shock waves occur as a result of a change in direction of the flow.

As with the nozzle, this is achieved either through the flow rate at the inlet being limited, or the formation of shock waves in the pipe ( for supersonic flows ).

In astrophysics, wherever there is evidence of shocks ( standing, propagating or oscillating ), the flow close by must be transonic, as only supersonic flows form shocks.

Supernovae explosions are accompanied by supersonic flows and shock waves.

A few seconds later, it erupted laterally, sending swift pyroclastic flows down its flanks at near supersonic speeds.
