Hypersonic flight vehicles (HFVs) have strong penetration and reconnaissance capabilities in military affairs

efficient deployment and space travel capabilities in civil use

making them one of the important ways for countries to construct strategic threats and compete for space resources. Hence

it draws much attention from many countries. The paper firstly reviews the development history and current research status of the HFVs

aiming to reveal the development principle. It is followed by the flight task analysis in different space domains ranging from orbiting space

near-space

and airspace. Then

the flight constraints and guidance methods for the reentry phase are mainly discussed

including offline reference trajectory-based guidance method

online trajectory-based guidance method

and prediction guidance method. Furthermore

the expectation of the future guidance system is given which lies in multi-constraints trajectory-based guidance method with high accuracy

nonlinear programming trajectory optimization-based guidance in real-time

and trajectory re-planning guidance technology with robustness to different tasks. Thirdly

the hypersonic flight control methods on solving the problem of high nonlinearity

uncertainty

time-varying

flexibility

input constraint

and system fault are summarized. Then

looking into the future

three aspects are discussed

including the deep mechanism analysis on system model/disturbance/fault

the control tradeoff when solving multiple problems

controller smooth switching technology

and autonomous hypersonic flight control in the present of the unexpected events. At last

the thinking on the HFV future development including hypersonic missile and reusable launch vehicle is provided

as well as the integrated guidance and control system design.
