However, they are characterized by high energy consumption. This article focuses on low-consumption electromechanical deicing solutions based on piezoelectric transducers. After a review of the state of the art to identify the main features of electromechanical de-icing devices, piezoelectric transducer-based architectures are studied. -

Computational Evaluation of Control Surfaces Aerodynamics for a Mid-Range Commercial Aircraft

The virtual experiments are performed at operational flight conditions, by resolving the mean turbulent flow field around a realistic model of the whole aircraft. The Reynolds-averaged Navier–Stokes approach is used, where the governing equations are solved with a finite volume-based numerical method. The effectiveness of the flight control system, during a hypothetical conceptual pre-design phase, is studied by conducting simulations at different angles of deflection, and examining the variation of the aerodynamic loading coefficients. The proposed computational modeling approach is verified to have good practical potential, also compared with reference industrial data provided by the Leonardo Aircraft Company. Keywords: computational fluid dynamics; flight control surfaces; industrial aerodynamics 1. Introduction Present trends in commercial aircraft design methodologies, which are mainly oriented toward cost reduction for product development, demand the accurate prediction of the control surfaces aerodynamics, to examine the aircraft flight control system early in the design process. -
Aircraft De-Icing/Anti-Icing
Aircraft De-Icing/Anti-Icing Standard Practices Procedure (1)Make sure that all loose snow is removed from the aircraft before you do the de-icing/anti- icing procedures. WARNING: FOR SUFFICIENT HOLDOVER TIME, MAKE SURE THE FREEZING POINT OF THE DE-ICING/ANTI-ICING MIXTURE IS LESS THAN THE AIRCRAFT AND AMBIENT TEMPERATURES. THE HOLDOVER TIME WILL ALSO DECREASE DURING THE CONDITIONS THAT FOLLOW: THERE ARE STRONG WINDS THERE IS PRECIPITATION THE AMBIENT TEMPERATURE DECREASES THERE ARE WINDS CAUSED BY OTHER AIRCRAFT ENGINES THE AIRCRAFT FUEL TEMPERATURE ADJACENT TO THE SKIN IS LESS THAN THE AMBIENT TEMPERATURE. IF YOU DO NOT OBEY THIS WARNING, THE HOLDOVER TIME WILL DECREASE. THIS CAN CAUSE INJURY TO PERSONS AND DAMAGE TO THE EQUIPMENT. WARNING: IF YOU DO THE ANTI-ICING PROCEDURE MORE THAN ONCE, DO THE DE-ICING PROCEDURE AGAIN ALSO. MORE THAN ONE LAYER OF ANTI- ICING WILL CHANGE THE AERODYNAMIC PROPERTY OF THE WINGS. THIS CAN CAUSE INJURIES TO PERSONS AND DAMAGE TO EQUIPMENT. (2)Obey the precautions and standard practices that follow when you do the de-icing/anti-icing procedures: (a)The APU should be shut down for all anti-icing/de-icing operations. (b)If it is necessary to operate the engines or the APU while you do the de-icing/anti-icing procedures, obey the precautions that follow: 1 Make sure that the engines are at idle speed. 2 Make sure that all bleed air valves are closed. 3 Make sure that all the external lights in the de-icing/anti-icing area are off. 4 Make sure the valves for the air conditioning unit are off. -
Improving Aircraft Performance with Plasma Actuators
Improving Aircraft Performance with Plasma Actuators Dr Huu Duc Vo Dr Njuki W Mureithi IMPROVING AIRCRAFT PERFORMANCE WITH PLASMA ACTUATORS Aeroplanes are required to change their trajectory many times during a flight. A system of adjustable surfaces that manage lift is typically used to meet this requirement. However, Dr Huu Duc Vo and Dr Njuki Mureithi from École Polytechnique de Montréal, Canada, have been working on a totally different approach to flight control – and it may eliminate the need for the adjustable surfaces, which can be inefficient, especially from an economics point of view. Engineering at École Polytechnique de Montréal, Canada, are among the leaders in the field of plasma actuation, and are seeking to establish their approach as an alternative to traditional flight control systems. Their ultimate goal is to improve aircraft performance and efficiency, resulting in cheaper aircraft acquisition and operating Dielectric Barrier Discharge actuator concept (left) and top view of plasma costs as well as lower aircraft carbon generated by actuator (right) emissions through a lighter, thus more fuel-efficient, airframe.

CONTROL SYSTEMS Introduction The architecture of the flight control system, essential for all flight operations, has significantly changed throughout the years. Soon after the first flights, articulated surfaces were introduced for basic control, operated by the pilot through a system of cables and pulleys. This technique survived for decades and is now still used for small airplanes. The introduction of larger airplanes and the increase of flight envelopes made the muscular effort of the pilot, in many conditions, not sufficient to contrast the aerodynamic hinge moments consequent to the surface deflection; the first solution to this problem was the introduction of aerodynamic balances and tabs, but further grow of the aircraft sizes and flight enveops brought to the need of powered systems to control the articulated aerodynamic surfaces. Nowadays two great categories of flight control systems can be found: a full mechanical control on gliders and small general
