The Development of a Civilian Fly by Wire Flight Control System
نویسنده
چکیده
Within a national research and development program funded by the german ministry of education and research (BMBF) new fly by wire flight control system has been developed and is in the process of certification according to JAR 25. Technology readiness was demonstrated for those technologies which are potential candidates for a new aircraft. New equipment was developed and demonstrated in several flights of the ATD (Aerospace Technologies Demonstrator) aircraft. The following new technologies have been demonstrated: cabinets for the computing system, smart actuator, electromechanical actuator, full fly by wire rudder and a hydraulic power package. For the first time the modular avionic approach was applied to a flight control system. As a result of this program each technology which is now approved by flight can be selected within future systems as building blocks and composed to systems (not only flight control) adequate for any aircraft type.

Evolution of Aircraft Flight Control System and Fly-By-Light Flight Control System
In past, the aircraft control systems were based on conventional methods of mechanical and hydro-mechanical system. The present generation aircraft are using fly-by-wire (FBW) and in future likely to migrate to fly-by-light (FBL) method for aircraft control system. Mechanical & Hydromechanical flight control systems have been replaced by FlyBy-Wire due to increasing speed of modern aircraft. Du...

At present, the use of unmanned aerial vehicles (UAVs) has been increased dramatically. The reasons for this development are cheapness, smallness, simplicity, and diversity of missions. The simplicity of guidance and control of multi-rotor drones is that they are equipped with an autopilot system. This system is responsible for flying control. UAVs do not have a high weight and often have three...

In wire arc spraying, the atomizing air pressure and applied nozzle system are important factors influencing particles characteristics and coating quality. The aim of this paper is to study how the characteristics of particles such as size, velocity and temperature are influenced by the operating conditions in wire arc spray. For that, three types of wires are tested: solid wire of stainless st...

INTRODUCTION Electronic controls systems have been used in commercial aviation for more than 40 years. With the introduction of the Concorde, the use of electronic systems (with mechanical backups) to manipulate the hydraulic controls used to fly by wire started the revolution on flight control. Digital systems were first used in the Airbus 310 where digital computers controlled flight control ...
