“…CTA MEMS hot-film sensors (Que et al , 2011; Zhu et al , 2009) have been developed and are used extensively, e.g. for laminar-turbulent transition in-flight monitoring (Marshall, 2000). Apart from knowing the transition/separation position, AoA and other parameters can be obtained from these sensors indirectly (Que and Zhu, 2012).…”

Purpose This paper aims to present a state-of-the-art review in various fields of interest, leading to a new concept of bio-inspired control of small aircraft. The main goal is to improve controllability and safety in flying at low speeds. Design/methodology/approach The review part of the paper gives an overview of artificial and natural flow sensors and haptic feedback actuators and applications. This background leads to a discussion part where the topics are synthesized and the trend in control of small aircraft is estimated. Findings The gap in recent aircraft control is identified in the pilot–aircraft interaction. A pilot’s sensory load is discussed and several recommendations for improved control system architecture are laid out in the paper. Practical implications The paper points out an opportunity for a following research of suggested bio-inspired aircraft control. The control is based on the artificial feeling of aerodynamic forces acting on a wing by means of haptic feedback. Originality/value The paper merges two research fields – aircraft control and human–machine interaction. This combination reveals new possibilities of aircraft control.

“…The scheme used an active flow control glove made from perforated titanium. Marshall (68) discusses variables that directly affect the ability to obtain laminar flow. While natural laminar flow can be achieved through aerofoil profile design in (40) • To perform sonic fatigue analyses on HSCT structural concepts to provide guidance to design teams.…”

A review of supersonic business jet design Issues

Key issues relating to the Supersonic Business Jet (SBJ) concept are reviewed with the intent to assess the readiness of enabling technologies and hence the concept itself. The multidisciplinary nature of aircraft design precludes an in-depth analysis of each specific aspect, which could individually be the subject of a separate discipline review, hence an overview is presented. The review looks at the market, environmental issues, with particular reference to the sonic boom phenomenon & solutions, technological issues, including prediction methods, flight testing, systems, certification and interested aerospace companies and design organisations. It is apparent that the need to reduce the sonic boom signature is vital if the vehicle is to be permitted to operate over land and hence be economically viable. It is clear that sonic boom acceptability requirements must be set if resources are to be effectively focused and designs are to converge. Despite this challenge, considerable investment is aimed at de-risking many of the enabling technologies and raising readiness levels. Many technologies are moving beyond theoretical and numerical analysis into the experimental and flight test domains. Collaboration between the civil and military sectors is increasing. Clearly, supersonic air travel is not an efficient means of personal conveyance; however, concerns for the environment are difficult to balance against the ‘value of time’ benefits offered by the SBJ concept. Air travel, of which this is a specialised form, is important to the global economy. Continued effort in the areas of human factors, customer demand and certification & requirements would be beneficial.

“…Let us mention that boundary control is of main importance in several branches of the industry, for instance in the aviation industry extensive research has been carried out concerning the implementation of injection-suction devices to control the motion of the fluid (see [3], [5], [6], [33], [40]).…”

Injection-Suction Control for Two-Dimensional Navier--Stokes Equations with Slippage

We consider a velocity tracking problem for the Navier-Stokes equations in a 2D-bounded domain. The control acts on the boundary through a injection-suction device and the flow is allowed to slip against the surface wall. We study the well-posedness of the state equations, linearized state equations and adjoint equations. In addition, we show the existence of an optimal solution and establish the first order optimality condition. (2000): 35D05, 76B03, 76B47, 76D09. Mathematics Subject Classification
