WebQuestion:-Bow shock wave During a reentry, the space shuttle orbiter experiences high supersonic speed ( M 1), associated with strong detached bow shock wave, as shown in the figure.Behind the shock wave, however, it can still be assumed that the flow is subsonic (isentropic and calorically perfect ideal gas of air). Webwith great force and this forms a shock wave much like a boat creates a bow wave. The bigger and heavier the aircraft, the more air it displaces. The Cause The shock wave forms a cone of pressurized air molecules which move outward and rearward in all directions and extend to the ground.
