The creation of an integrated rotorcraft conceptual and preliminary design framework at DLR involved the development of geometry and fuselage aerodynamics modules at the Institute of Aerodynamics and Flow Technology. After a short revision of the RIDE rotorcraft design environment architecture this paper focuses on the implementation of these disciplinary modules. The aim of the geometry module...

Temperature regulating system by gaseous nitrogen is of importance to the space environment simulator, which keeps the shrouds in the temperature range from -150°C to +150°C. Liquid nitrogen spray equipment is one of the most critical parts in the temperature regulating system by gaseous nitrogen. Y type jet atomizer and internal mixing atomizer of the liquid nitrogen spray equipment are studie...

This study aims to design a morphing winglet structure for the CRJ-700 regional transport aircraft. The technology is applied on winglets demonstrate significant increase of aerodynamic performance From data LARCASE Virtual Research Simulator VRESIM, benefits in cruising phase were obtained through ParaView software. was drawn using CATIA V5; this new concept included several structural compone...

1. MECHATRONIC SIMULATION Simulation tools like SPICE for electronics and CATIA for mechanics are widely available and used for verification of the performance of electrical or mechanical devices and systems. For electromechanical systems, interaction between electronics and mechanics is often essential for system functionality. A mechatronic simulation tool should be added to CAD environment, ...

Due to the inherent nature of combustion in the Cylinder of a Conventional Internal combustion engine, stress variation as well as a certain temperature distribution sets up in the entire piston. Analysis of piston is required because of its shape and it is subjected to both structural and thermal loads. In the present study, piston of a two stroke spark ignition internal combustion engine havi...

he present paper deals with the study of static and dynamic analysis of transmission line tower (X type of bracing system). A typical type of transmission line tower carrying 220KV single circuit conductor is chosen as case study existing in bijapur district. The analysis and modeling of tower is carried out using FE based ANSYS software. The model is created in CATIA and then imported to ANSYS...

The responses of the structures used in engineering applications under effects static and dynamic forces are significant design phase. Determination response for a structure is initially performed by evaluation free vibration characteristics that mode shape frequencies. This paper presents modal analyses tapered aircraft wing consist NACA4415 different common materials aviation industry. Furthe...
