1 Hypersonic aircraft refers to the speed of sound, at least 5 times more than the aircraft.

2 The results indicate that the starting characteristics of hypersonic inlet is greatly influenced by inner contractive ratio, the first wedge angle and the blunted wedge of the cowl.

3 Hypersonic aircraft to fly faster secret lies in its use of a ram - jet engine.

4 Numerical methods for hypersonic flow with chemical non-equilibrium reactions on the unstructured grid are used to analyze the drag induction of channel-configurations.

5 Hypersonic wind tunnels operating at very low densities were developed starting in about 1960.

6 The forebody design a key issue for hypersonic airbreathing vehicle.

7 A new method of quickly hypersonic waverider forebody configurations was developed.

8 America's forthcoming "Prompt Global Strike" non-nuclear hypersonic missiles will be able to hit almost any spot on earth in less than an hour—provided excellent satellite data is available.

9 Hypersonic propulsion test facility is important for the scramjet ground tests.

10 The results of numerical simulation of the hypersonic flow around a plate with a sharp leading edge are presented.

11 Hypersonic vehicle must be designed in integration methodology for the strong coupling effect of the subsystems.

12 The result of this is that the molecules are actually accelerated further and travel at hypersonic velocity out of the engine bell.

13 Because turbine based combined cycle has mature turbine technology, being contrasted with other types of combined cycle engines it has more attraction for hypersonic speed prolusion system.

14 Metallic thermal protection system a feasible solution for thermal protection of hypersonic vehicles.

15 This paper presents a numerical analysis of inviscid equilibrium and nonequilibrium hypersonic flow past blunt-nosed slender cones.

16 The nature of an open separation has been analysed qualitatively and the numerical simulation has been made for the hypersonic flow with an open separation over the blunt cone at angle of attack.

17 In paper, the scheme, model and algorithm of navigation for hypersonic cruise craft have been studied.

18 Achieving that speed is possible thanks to the craft's specialized rocket engine, a hypersonic scramjet.

19 The objective of the test is to collect data on hypersonic boost-glide technologies and test range performance for long-range atmospheric flight.

20 Based on the piston theory of supersonic flow, the second lagrange equation is used to set up the dynamic equations of an airfoil with store in the supersonic or hypersonic flow.

21 Thus it was extensively applied to experimental research of transonic and hypersonic flow.

22 A sliding mode observer is designed to estimate the angle of attack and flight path angle for a hypersonic vehicle.

23 Some kinds of Newtons theory of collision methods is extended to calculate the supersonic and hypersonic missiles with large slenderness ratio.

24 The analysis and computation of chemical non - equilibrium hypersonic wakes are important tasks of reentry aerodynamics.

25 As the earth rotation cannot be safely ignored in long-range hypersonic entry condition,[www.Sentencedict.com] an integrated quasi-equilibrium glide condition is presented.

26 Atmospheric reentry generates tremendous heating on the undersurface of spacecraft (a couple of thousand degrees Celsius) caused by the friction of the air rushing by at hypersonic speeds.

27 An engineering formula for estimating turbulent base heat transfer of hypersonic flow is given on the basis of flight data and the experimental results in shock tunnel.

28 With such a large heat sink value, FRA can meet the requirement of hypersonic flying machine.

29 The paper widens the application of local method which used to be utilized in rarefied flow to the quick prediction of aerodynamic characteristics of missile-like reentry vehicle in hypersonic flow.

30 It′s necessary to recognize the different vortices, when aero-optical distortion caused by hypersonic flow is studied using vortex structure as the turbulence model.
