MODELS AND PROBES Aerolab produces five Drag Models for the Educational Wind Tunnel. These models can be used for both flow visualization and force measurements because they easily mount onto the sting balance. The models are in the form of a teardrop, a backward-facing semi-spherical shell (cup), a sphere, a forward-facing semi-spherical shell (cup) and a circular flat plate. Aerolab supplies a 1:48th scale model of the famous General Dynamics F-16 fighter. Our model is resin-filled for greater strength, stiffness and durability. It mounts easily to any 3/8” sting balance with one set screw for both flow visualization and force measurements. The overall length is 11.5 inches and the span is 7.5 inches. The Aerolab Flat Plate and Mouse combination is a convenient way to demonstrate, and study, boundary layers and boundary layer growth. The 10-tap total pressure probe, or “mouse”, can be positioned in three locations along the length of the flat plate. The pressure probes ascend on an angle covering a width of one inch and a height of 0.24 inches. The probes are approximately 0.048 inches apart along the diagonal. Our Aerolab Pitot-Static Tube mounts in the Educational Wind Tunnel through the test section side windows. Its position in the flow can be adjusted and locked. The tube features a rounded-tip total-pressure tap and 6 static ports. It reaches 2.6 inches forward of the bend, extends 13 inches to the bend, and has an OD of 0.125 inches. Aerolab supplies ample tubing to connect the tube to your choice of indicators. The Aerolab Pressure Cylinder mounts vertically and spans the test section of the Educational Wind Tunnel. It has 24 flush-mounted pressure taps along its circumference. After being adjusted manually, the angular position is read from the turntable scale. The Pressure Cylinder has an outside diameter of 4 inches and is supplied with all necessary tubing to connect it to the Aerolab Pressure Selector Valve. The Aerolab Pressure Wing mounts vertically and spans the test section of the Educational Wind Tunnel. It has 18 flush-mounted pressure taps around its Clark Y-14 airfoil. After being adjusted manually, the angle of attack is read from the turntable scale. The Pressure Wing has a chord of 3.5 inches and is supplied with all necessary tubing to connect it to the Aerolab Pressure Selector Valve. Our Aerolab Clark Y-14 Slat/Flap Wing features adjustable slats and flaps. It mounts onto any 3/8” sting balance and can be used for both flow visualization and force measurements. The model spans 9.875 inches and has a chord of 3.5 inches. The Aerolab Turbulence Sphere is 4 inches in diameter, highly polished and equipped with a 3/8 inch sting mounting post. Critical Reynolds number is determined with balance data as the sphere has no pressure taps. The Aerolab Wake Rake has 18 total-pressure taps and mounts into the Educational Wind Tunnel test section through the turntable. The ports span approx. 1.75 inches and are 2.125 inches in front of the 90° bend. The Wake Rake is 10 inches long and is supplied with all necessary tubing to connect it to the Aerolab Pressure Selector Valve. There are three ports in the tip of our Aerolab Yaw Probe. The probe has an overall length of 10.5 inches, an O.D. of 0.125 inches, and mounts easily in the test section of the Educational Wind Tunnel. It features a machined aluminum triangle at its base which can be adjusted once the probe is calibrated. This triangle then shows the orientation of the ports from outside the test section and acts as a handle for quick, accurate angular changes. The Yaw Probe is supplied with ample tubing to connect it to your choice of indicators.
