Retarded Harrier Maneuver as a New and Efficient Approach for fixed-wing aircraft to Achieve S/VTOL

Advances in Aerospace Science and Technology 2021年第2期6卷 81-92页

作者： Chung-Kiak Poh Chung-How Poh Aero-Persistence Research Penang Malaysia

Modern day VTOL fixed-wing aircraft based on quadplane design is relatively simple and reliable due to lack of complex mechanical components compared to tilt-wings or tilt-rotors in the pre-80’s era. Radio-controlled aerobatic airplanes have thrust-to-weight ratio of greater than unity and are capable of performing a range of impressive maneuvers including the so-called harrier maneuver. We hereby present a new maneuver known as the retarded harrier that is applicable to un/manned fixed-wing aircraft for achieving VTOL flight with a better forward flight performance than a quadplane in terms of weight, speed and esthetics. An airplane with tandem roto-stabilizers is also presented as an efficient airframe to achieve VTOL via retarded harrier maneuver, and detailed analysis is given for hovering at 45° and 60° and comparison is made against the widely adopted quadplane. This work also includes experimental demonstration of retarded harrier maneuver using a small remotely pilot airplane of wingspan 650 mm.

Distributed formation control of multiple aerial vehicles based on guidance route

Chinese Journal of Aeronautics 2023年第3期36卷 368-381页

Formation control of fixed-wing aerial vehicles is an important yet rarely addressed problem because of their complex dynamics and various motion constraints,such as nonholonomic and velocity constraints.The guidance-route-based strategy has been demonstrated to be applicable to fixed-wing aircraft.However,it requires a global coordinator and there exists control lag,due to its own natures.For this reason,this paper presents a fully distributed guidance-route-based formation approach to address the aforementioned issues.First,a hop-count scheme is introduced to achieve distributed implementation,in which each aircraft chooses a neighbor with the minimum hop-count as a reference to generate its guidance route using only local information.Next,the model predictive control algorithm is employed to eliminate the control lag and achieve precise formation shape control.In addition,the stall protection and collision avoidance are also considered.Finally,three numerical simulations demonstrate that our proposed approach can implement precise formation shape control of fixed-wing aircraft in a fully distributed manner.

The flight ability will be affected, and the flight path will be deviated from the desired trajectory when wing damage of the fixed-wing aircraft happen in flight. More seriously, the fixed-wing aircraft will be loss-of-control as a result of severe situations. A method of quantitative estimation the wing damage degree of fixed-wing aircraft is proposed in this paper. In this method, MMAE method is not only used to solve the problem of parameter estimation which is difficult to establish an analytical formula between the system state and the parameter of wing damage, but is also used to improve the accuracy of estimation in the case of large difference between the actual wing damage and the presupposed damage. The simulation results show that the proposed estimation method can accurately estimate the wing damage degree of the fixed-wing aircraft.

In this paper, based on sliding mode technique, a finite-time formation control method under constrained velocity and acceleration for fixed-wing aircraft is proposed, which is applied to formation and switching of formation, and the formation of maneuver trajectory is realized. Its finite time convergence under constrained velocity and acceleration is proved, and the simulation results show that the method is effective.

丛书名： AIAA Education Series

2003年

作者： Robert E. Ball

ISBN: (数字)9781600862519

ISBN: (纸本)9781563475825

Winner of the Summerfield Book Award!aircraft combat survivability is now an established design discipline for U.S. military aircraft. More importantly, survivability is now an essential part of the U.S. Department of Defense acquisition process. This is the only book of its kind and required reading for anyone involved in design of air combat vehicles. Further, improving public health, safety, and survivability is now woven throughout the civil and commercial sector. From infant car seats to the design of aircraft cargo bay structure that can withstand internal bomb blasts, the government is taking the lead in establishing survivability standards. This is an extensively illustrated text that presents the fundamentals of the aircraft combat survivability design discipline as defined by the DoD Military Standard issued in 1981. It provides the history of, the concepts for, and the assessment methodology and the design technology for the nonnuclear combat survivability analysis and design of fixed and rotary wing aircraft and missiles. Of critical interest to anyone involved in the design and development of military aircraft or airborne weapon systems, the book also will be useful to weapon system effectiveness analysts.The Fundamentals of aircraft Combat Survivability: Analysis and Design on CD-ROM is included with your purchase of the hardcover. The CD-ROM gives you the portability and searchability that you need in your busy environment. It is considerably smaller and lighter than the textbook so it is available when you are away from the office or traveling. It can also be searched to quickly locate a particular word or phrase.

Flight Vehicle Performance and Aerodynamic Control

丛书名： AIAA Education Series

Flight Vehicle Performance and Aerodynamic Control is designed to serve as a text for either an 11-week or a 16-week course at the sophomore level. It explains typical methods used to estimate aircraft performance, the theoretical basis of these methods, and how various parameters derived from the aircraft geometry can be used to estimate the requirements of control surfaces and the aerodynamic forces required to actuate these surfaces. This book includes time-tested computer programs that perform the analyses in a manner that reduces student error and improves result accuracy. Because the source code is given, users with a FORTRAN compiler can modify the program to suit particular needs. The major advantage of the software is that more realistic problems may be treated and the effects of parametric programs are more accurate than calculators. The programs are available as executables for Windows machines as well as in ASCII source code versions that can be readily compiled and then executed on Unix, Linux, and Macintosh machines, and on mainframes.
