The Role of Guidance, Navigation, and Control in Hypersonic Vehicle Multidisciplinary Design and Optimization

Abstract

Airbreathing hypersonic systems offer distinct performance advantages over rocket-based systems for space access vehicles. However, these performance advantages are dependent upon advances in current state-of-the-art technologies in many areas such as ram/scramjet propulsion integration, high temperature materials, aero-elastic structures, thermal protection systems, transition to hypersonics and hypersonic control elements within the framework of complex physics and new design methods. The complex interactions between elements of an airbreathing hypersonic vehicle represent a new paradigm in vehicle design to achieve the optimal performance necessary to meet space access mission objectives.

A new tightly-coupled INS/CNS integrated navigation algorithm with weighted multi-stars observations

“…In classic framework of INS/CNS integrated navigation, the position ðl C , L C Þ is solved first in CNS through iteration of equation (2) according to observed elevation angle h C . 10,20 Then the result of CNS localization is integrated with INS, like a ''looselycoupled'' model.…”

“…1 Due to the high dynamic characteristics of the HCVs, elevated accuracy and reliability are required for its autonomous navigation systems. 2 The embedded GPS/INS system (EGI) is a navigation equipment widely used in aircrafts. [3][4][5] Nevertheless, vehicles flying at hypersonic velocities would be enveloped in a ''plasma sheath'' that prevents radio communication, telemetry and, most importantly, GPS signal reception for navigation.…”

Fuzzy-Approximation-Based Novel Back-Stepping Control of Flexible Air-Breathing Hypersonic Vehicles with Nonaffine Models

“…With the increasing extension of human activities to space, highvelocity and high-altitude vehicles represented by airbreathing hypersonic vehicles will play an important role in the field of aerospace. The control system is the "nerve center" of an aircraft, and the design of the AHV control system has become one of the frontier issues in the field of control science [1].…”

“…∉ Ω e h,1 or e h,4 ∉ Ω e h,4 or e h,2 ∉ Ω e h,2 or e h,3 ∉ Ω e h,3 or φ 1 ∉ Ω φ 1 , W h will be negative. It is clear that e h,1 , e h,4 , e h,2 , e h,3 and φ 1 are semiglobally uniformly ultimately bounded.…”

Collaborative Deformation Design Using Control Integrated Analysis Methods for Hypersonic Waverider

“…This is due to the presence of the complex interactions in a hypersonic vehicle, involving aerodynamics, propulsion, control, and so on. Meanwhile, the highly integrated dynamics of the hypersonic vehicle require a tightly integrated design process [5]. Therefore, the considerations of the control-related tradeoff design will assist to impose serious compromises in both system cost and quality of overall performance for hypersonic vehicles [6].…”
