The aim of this paper is to present and discuss the experience in policy evaluation methods and practices related to large-scale technological programmes. The presentation will rely on the evaluation of the European space programmes, as an archetype of technological (“mission-oriented”) programmes focused on a highly specific and narrowly predetermined end product (such as a launcher or a satel...

A dedicated optical system is designed for the breakdown of first ITER plasma, when machine will not be equipped with equatorial ECRH-launcher. Seven beams from upper launcher transmitted via several in-vessel mirrors through resonance layer to a beam-dump. The whole was simulated PROFUSION package obtain beam parameters, estimate spill-over effects and determine required polarization in order ...

During the last five years, Oerlikon Aerospace developed and implemented engineering processes. In this paper, we discuss the application of risk management to the re-engineering of operator console stations of a missile weapon system. We briefly describe the systems engineering process. Finally, twelve lessons learned are discussed. PROCESS DEVELOPMENT BACKGROUND Oerlikon Aerospace (OA) is the...

Europeans will soon send inhabited missions into space with the Ariane 5 launcher and spaceshuttle Hermes combination. In case of an incident at launch, either on the pad or up to some speed after launch, it is proposed toeject the flightcrew tosafety on individualejectorseats. The risks which would be confronted by the astronauts

In the large helical device (LHD), direct oblique launching of the extraordinary (X-) mode from the high magnetic field side is available without installation of any additional mirror or installation of a launcher in the inner side of the torus. The launched X-mode first encounters the electron cyclotron resonance (ECR) layer from the high magnetic field side and then approaches the upper hybri...

Most aircraft launchers exhibit a rapid acceleration of the launching aircraft, often exceeding ten times due to gravity. However, only magnetic offer flexible control over propulsion force launcher cart, enabling precise aircraft’s and speed during its movement on launcher. Consequently, extensive research is being conducted ensure repeatability launch parameters, protect against overloads, op...

Grenade launchers renew the interest for the interior ballistic principle of high/low pressure chambers which is applied in them. In this paper for the sake of optimization in the specific grenade launcher the theoretical investigations are carried out. In theoretical modeling special attention is paid to flow of two- phase mixture of propellant gases and unburned propellant from the high -pres...
