Adaptive Higher Order Continuous Sliding Mode Integrated Guidance and Control With Neural Disturbance Compensation for Intercepting Maneuvering Targets

Modelling and Simulation in Engineering, Volume 2026, Issue 1, 2026.
Existing integrated guidance and control (IGC) schemes often face a trade‐off between chattering suppression and rapid adaptability, particularly when relying on single‐parameter tuning or discontinuous switching laws. To bridge this gap, this paper proposes a novel adaptive continuous higher order sliding mode controller (ACHOSMC) designed for ...

System controls challenges of hypersonic combined-cycle engine powered vehicles [PDF]

Hypersonic aircraft with air-breathing engines have been described as the most complex and challenging air/space vehicle designs ever attempted. This is particularly true for aircraft designed to accelerate to orbital velocities.

A Data‐Driven Approach to Integrated Adaptive Morphing and Guidance for Cruise Missiles

International Journal of Mechanical System Dynamics, Volume 5, Issue 4, Page 670-693, December 2025.
ABSTRACT To address the complex coupling between aerodynamic characteristics and guidance control for morphing flight missiles, this study proposes a data‐driven approach to integrated adaptive morphing and guidance. Firstly, an aerodynamic surrogate model is constructed using a fully connected neural network (FCNN), mapping the configuration ...

The Optimization Design of a Compact Integrated Precooler for Advanced Space Launcher Engines

Chemical Engineering Transactions, 2020
In recent years, aeroplane engines have evolved towards the direction of hypersonic flight, re-use and combined cycle propulsion. As one of the core components, air-hydrogen precooler plays a vital role in the development of liquefied air cycle engines ...

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

Advanced Engineering Materials, Volume 27, Issue 22, November 2025.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Optimum Design of Hypersonic Airbreathing Propulsion.

JOURNAL OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, 2002
The flight of Spaceplane is always under accelarating in the assent way and always under decelarating in the desent way and yet cruising in the return way. Besides, its flight envelope is considerably wider than that of airplane. Thus the integrated design method is required to build the best transportation system optimized taking into account the ...
