This paper describes a full-scale, flexible test vehicle designed and built by the original equipment manufacturer (OEM) to validate the aerodynamic and mechanical performance of large compressors for a variety of applications. This paper provides a description of the test vehicle as well as mechanical and aerodynamic performance data gathered during testing of the vehicle.

The steady and unsteady aerodynamic behaviour of a sailing yacht is investigated in this work by using full-scale testing on a Stewart 34. The aerodynamic forces developed by the yacht in real time are derived from knowledge of the differential pressures across the sails and the sail shape. Experimental results are compared with numerical computation and good agreement was found.

In this paper, an intelligent algorithm for the aerodynamic parameter calibration of wind tunnel experiments advanced layout aircraft at a high angle attack is proposed. The proposed based on homologous comparison and tuning algorithm, it can effectively improve accuracy experiment model. First, analysis large oscillation experimental data scaled aircraft, model composed static derivative, dyna...

Considering rotation-induced centrifugal stiffening, spin softening, and Coriolis effects, the reduced dynamic model of a rotating blade with dovetail fixture is established in ANSYS environment via fixed-interface method for higher computational efficiency lower memory consumption. Then some parameters such as speed, friction factor, stator number affecting nonlinear vibration responses system...

Reduction of the aerodynamic noise generated by pantographs is a matter of great important for further speedup of the high speed trains. In general, pantographs are composed of some kind of bluff bodies. Therefore, the method to reduc e the aerodynamic noise generated by bluff bodies is demanded. In this paper, we will present the noise reduction effect of cylinder by equipping intermittent hol...

In the present work, aerodynamic performance of Caradonna and Tung S-76 in hover were investigated using a simplified concept multiple reference frame (MRF) technique context high-order Monotone Upstream Centred Scheme for Conservation Laws (MUSCL) cell-centred finite volume method. methodology, is defined at solver level by simple user input avoiding use mesh interface to handle intersections ...
