An overview on dynamics and controls modelling of hypersonic vehicles [PDF]
2009 American Control Conference, 2009 In order to appropriately design control laws for hypersonic vehicles, it is paramount to understand how the flight dynamics are impacted by the interactions between the aerothermodynamics, propulsion system, structural dynamics, and control system. To this end, there has been a significant investment into the modelling of these sub-systems and their ...

Forebody Compressibility Research of Hypersonic Vehicle
, 2004 Three kinds of forebody model of hypersonic vehicles were studied with numerical simulation method. It shows that the two- order compressive ramp model is the best selection among the three for its good evaluative parameters value at the cowl of the ...
