Expansion of existing facilities; appropriations; testing of models -STATUTE- (a) The Administrator is authorized to expand the facilities at his existing laboratories and centers by the construction of additional transsonic, supersonic, and hypersonic wind tunnels, including buildings, equipment, and accessory construction, and by the acquisition of land and installation of utilities.
Such tests shall be scheduled and conducted in accordance with industry's requirements and allocation of facility time shall be made in accordance with the public interest, with proper emphasis upon the requirements of each military service and due consideration of civilian needs.

 3 Numerical solutions   (Site not responding. Last check: 2007-11-04)
Velocity is subsonic at the base of the wind and the gas pressure falls to zero at infinity (Mihalas 1978).
The shooting-splitting method is carried out until the relation (82) between the gas and the grain velocities is satisfied, with an accuracy roughly equal to that of the shooting-splitting method.
When dynamics is coupled with the radiative transfer, the main difficulty encountered is the uncertainty of the existence of a critical point and a transsonic solution at each iteration.

As designers and test pilots pushed their planes up toward the speed of sound, the danger they feared most was the beating they took in the "transsonic zone." When an airplane is moving close to sonic speed, shock waves'(powerful sound waves) form on its wings and control surfaces.
Above the transsonic, the designers hoped, the air would be easier to cope with.
The Skyrocket was designed to minimize transsonic buffeting, and the rockets push it quickly to high supersonic speed.

This is the freestream Mach number at which M=1 is reached somewhere in the flow (normally on a wing upper surface).
From this Mach number up to full supersonic flow it is necessary to solve the transsonic equation.
By using the correct area distribution, transsonic wave drag can be significantly reduced.

 Towards Mach 2: The Douglas D-558 Program   (Site not responding. Last check: 2007-11-04)
Obviously, the transsonic gap (between Mach.75 and Mach 1.3) needed further research.
The first three aircraft, D-558-1s, were comparable to the Bell X-1 in that they allowed engineers to study transsonic speeds and compressibility problems.
Unlike the Bell X-1, the D-558-1 could loiter in the transsonic region and bring back much more data, which showed that in that region, lateral stability deteriorated, wing dropping occurred, and trim was affected.

It is important to note that teoretical principles of apparatus work were elaborated by Professor Fisenko V.V. in the beginning of 70th years.
Then Engineering Center “Transzvouk” (Ukraine, 1986) and companies in Bulgaria (“Transzvouk”, 1987–1990), Munich (“Transsonic”, 1990–1995), Austria (“Transsonic”, Vienna, 1996), USA («Fisonic», New York, 1996 – present time), Moscow (“Fisonic-Fisenko” Ltd) were organized for broad-scaled inculcation of on principle new technical solutions – “transsonic devices”.

 Cloudy Globule   (Site not responding. Last check: 2007-11-04)
This succeeds at forcing a transsonic solution after a few iterations.
However, on the next iteration it switches back to a weak-R solution because the advected terms have changed enormously within one advection length downstream of where the sonic point was, depressing the sound speed there so that the Mach number no longer dips down enough.
It is trying to go through the sonic point before the c-squared max has been reached, so it has a sequence of pressure failures before getting out the other side.

 Theodore von Karman
In 1944 he chaired the Army Air Force's newly-created Scientific Advisory Group, which studied the then-cutting edge technologies in rocketry, guided missiles, and jet propulsion.
His important theory of boundary layers and his related studies of fluid flow at high subsonic, transsonic, and supersonic speeds were of great importance to post-World War II progress in all areas of flight.
Personally, von Karman was known as a colorful, multilingual character who enjoyed entertaining a diverse circle of friends and acquaintances.

 Airliners.net forum: Sonic Cruiser Needs Some Changes
Firstly, i think THE biggest problem will be transsonic drag, which will be HUGE where the SC is planning to fly at.
That would cause BIG problems at transsonic speeds, and semi-buried engines like Boeing's SC design has would be better.
As you mentioned, the biggest problem for Boeing is that a lot of the stuff on the SC is new for them.

 NASA - NASA History in Brief
The watershed F-8 digital-fly-by-wire program laid the groundwork for such electronic flight in many other aircraft including the Shuttle and high performance airplanes that would have been uncontrollable otherwise.
NASA has also done important research on such topics as "lifting bodies" (wingless airplanes) and "supercritical wings" to dampen the effect of shock waves on transsonic aircraft.
Additionally, NASA has launched a number of significant scientific probes such as the Pioneer and Voyager spacecraft that have explored the Moon, the planets, and other areas of our solar system.
