This paper is primarily concentrated with determining aerodynamic characteristics and choosing the best angle of attack at a maximum lift and low drag for the FX aerofoil at a low Reynolds number and a speed of 20m/s and 30m/s, by using subsonic wind tunnel through manufacturing the aerofoil by aluminum alloy using a CNC machine. The proposed methodology is divided into several by: 1. Tests have been made in the 3ft x 3ft wind tunnel at RAE Bedford on a scale model of the AVRO aircraft to investigate the longitudinal stablllty characteristics at Mach numbers between and AddItional tests were made with airbrakes attached to the rear-fuselage and wthFile Size: 1MB.
Report presenting tests in the 4- by 6-foot vertical wind tunnel of an NACA airfoil with a percent-chord flap with a small amount of aerodynamic balance. In the investigation, the effect of balance nose shape and gap at the nose of the flap has been determined. The results indicate that, in general, the lift effectiveness of the flap was unaffected by the addition of a small amount of Author: Milton B Ames.

Aerodynamic characteristics of the wing are subjected to dramatic changes due to the flow field interference with the ground. In the present paper, the wing-ground collision was investigated experimentally and numerically.
The investigation involved a series of wind tunnel measurements of a 2-D wing model having. supersonic wind tunnel (continuous) A suction-type continuous-operation supersonic wind tunnel for investigations into subsonic and supersonic air flow.
It also allows students to study air flow in two dimensions around aerodynamic models. An investigation was made to determine the effect of various high lift devices on a highly sweptforward wing with a leading edge sweep angle of 55 degrees and on a straight wing, both wings having an aspect ratio of and the same span.
Experimental tests were made in the Cal Tech - Merrill low speed wind tunnel at Pasadena City College on both types of wing with and without : J. Densmore. speed wind-tunnel investigation of the longitudinal aerodynamic characteristics of a supersonic airplane configuration utilizing high-performance auxiliary parawings having both rigid and flexible leading edges.

An intermittent operation, induction-type supersonic wind tunnel for investigations into subsonic and supersonic flow. This includes tests on the flow around two-dimensional models at subsonic and supersonic air speeds. A compressed air supply (AFb, available separately) induces a flow in the working section of the wind tunnel.
The goals of this project were to design and construct a supersonic wind tunnel with diagnostic and visualization systems to characterize flow properties. The supersonic wind tunnel was designed to interface with a vacuum chamber in the Vacuum Test Facility (VTF) at Worcester Polytechnic Institute.

A new experimental investigation approach of a moving vehicle device is proposed to investigate the aerodynamic characteristics of moving vehicles on bridges under crosswinds.
The new moving vehicle device, which can adjust the incoming wind directions and wind attack angles, consists of a vehicle, bridge segment, and motion system by: 9. Possessing both theoretically predicted aerodynamic characteristics and wind tunnel test data for the same six airfoils provides an extraordinary opportunity to compare the performance, measured by energy capture, of wind turbine rotors designed with the diﬀerent data.
This will provide the insight needed to assist designers in deciding. Numerical Investigation of Wind Tunnel all Effects on a Supersonic Finned Missile Loai A. Elmahdy*, M.Y.M Ahmed*, O.K.

Measurement of aerodynamic forces. Air velocity and pressures are measured in several ways in wind tunnels. Air velocity through the test section is determined by Bernoulli's ement of the dynamic pressure, the static pressure, and (for compressible flow only) the temperature rise in the airflow.
The direction of airflow around a model can be determined by tufts of yarn attached. Similarity analysis applied to vehicles using wind tunnel  Motivation . With new models of vehicles always being created, wind tunnel testing is needed to evaluate the complex turbulent flow around the vehicle to better understand the capabilities and restrictions of new models and optimize the aerodynamics of new vehicles in wind tunnels.wind-tunnel investigation at subsonic and supersonic speeds of a model of a tailless fighter airplane employing a low-aspect-ratio swept-back wing-stability and .Wind tunnel tests were carried out to obtain the static aerodynamic characteristics of crescent iced 4-bundled conductors with different ice thicknesses, initial ice accretion angles, bundle spaces, and wind attack angles.
