This paper focuses on the analysis of high-temperature effect on a conical waverider and it is a typical configuration of near space vehicles. Two different gas models are used in the numerical simulations, namely the thermochemical non-equilibrium and perfect gas models. The non-equilibrium flow simulations are conducted with the usage of the parallel non-equilibrium program developed by the authors while the perfect gas flow simulations are carried out with the commercial software Fluent. The non-equilibrium code is validated with experimental results and grid sensitivity analysis is performed as well. Then, numerical simulations of the flow around the conical waverider with the two gas models are conducted. In the results, differences in the flow structures as well as aerodynamic performances of the conical waverider are compared. It is found that the thermochemical non-equilibrium effect is significant mainly near the windward boundary layer at the tail of the waverider, and the non-equilibrium influence makes the pressure center move forward to about 0.57% of the whole craft's length at the altitude of 60 km. ª 2015 Production and hosting by Elsevier Ltd. on behalf of CSAA & BUAA.

“…Because of this advantage, the concept has received a lot of attention over the years after its inception by Nonweiler in 1959 [7]. In the wake of the arrival of a family of viscous optimized waveriders [8], a lot of literature about their design methodologies [9][10][11][12], performance evaluations [13][14][15][16][17][18][19], and proposed applications [20][21][22][23][24][25] was published.…”

This paper proposes a family of high-pressure capturing wing configurations that aim to improve the aerodynamic performance of hypersonic vehicles with large volumes. The predominant visual feature of such configurations is a thin wing called a high-pressure capturing wing attached to the top of an upwarp airframe. When flying in the hypersonic regime, high-pressure airflow compressed by the upper surface of the vehicle acts on the high-pressure capturing wing and significantly augments lift on the vehicle with only a small increase in drag, producing a correspondingly high increase in its lift-to-drag ratio. A series of numerical validations were carried out on the basis of both inviscid and viscous computational models in which ideal cones with different cone angles and combined conewaverider bodies with different volumes were used as airframes. The results clearly demonstrate that a configuration using a high-pressure capturing wing has a significantly higher lift (with a correspondingly high value of lift-to-drag ratio) than one without a high-pressure capturing wing, especially for vehicles with large volumes. This paper contains a preliminary, results-based report of the conditions under which high-pressure capturing wing configurations were tested.= cruising speed W = gross weight, width α = angle of attack β = shock-wave angle γ = ratio of specific heats Δn = nondimensional height of the first layer near the wall η = ratio of average pressure on different surfaces θ = wedge angle, half-cone angle ξ = volumetric efficiency ρ = density Subscripts B = body H = high-pressure capturing wing HCWL = lower surface of the high-pressure capturing wing HCWU = upper surface of the high-pressure capturing wing

“…Two forebody configurations were designed and the flowfields around them were computed to examine the characteristics. A Mach 6 baseline waverider for creating the forebody was generated by using the codes GCBWRG developed by Cui et al 26,27 . The intersection angle between the two leading edges is 90 degree.…”

A design methodology employed for a practical preliminary-level integration of next generation hypersonic airplanes is presented in this paper. The key feature of this type of configurations is that the forebody of the vehicle is designed by rotating and assembling two waverider-based-surfaces, which are defined by linear edges. The propulsion system assumes two scramjets with cylindrical combustion chambers. The layout of the configuration presents a Blend-Wing-Body aircraft in order to integrate the airframe and the propulsion units as well as to improve the aerodynamic performance. Nomenclature
