INCAS TRISONIC WIND TUNNEL
Journal Title: INCAS BULLETIN - Year 2009, Vol 1, Issue 1
Abstract
The 1.2 m x 1.2 m Trisonic Blowdown Wind Tunnel is the largest of the experimental facilities at the National Institute for Aerospace Research - I.N.C.A.S. "Elie Carafoli", Bucharest, Romania. The tunnel has been designed by the Canadian company DSMA (now AIOLOS) and since its commissioning in 1978 has performed high speed aerodynamic tests for more than 120 projects of aircraft, missiles and other objects among which the twin jet fighter IAR-93, the jet trainer IAR-99, the MIG-21 Lancer, the Polish jet fighter YRYDA and others. In the last years the wind tunnel has been used mostly for experimental research in European projects such as UFAST. The high flow quality parameters and the wide range of testing capabilities ensure the competitivity of the tunnel at an international level.

Stress analysis of toroidal shell
Stress analysis for a toroidal shell used for a flying platform. We will be comparing the results obtained by classical approach and by numerical method (finite element analysis).
Unsteady Flow in a Horizontal Double-Sided Symmetric Thin Liquid Films
In this paper a mathematical model is constructed to describe a two dimensional incompressible flow in a symmetric horizontal thin liquid film for unsteadies flow. We apply the Navier-Stokes equations with specified boun...
Global and local stability and instability of the constant spatially developing gas flow
In this paper different types of stabilities (global, local) with respect to instantaneous perturbations and permanent source produced time harmonic perturbations are presented in case of a spatially developing gas flow....

[b]Prediction of pilot induced oscillations[/b]
An important problem in the design of flight-control systems for aircraft under piloted control is the determination of handling qualities and pilot-induced oscillations (PIO) tendencies when significant nonlinearities e...
