Problem 1: A wing with an elliptical planform and an elliptical lift distribution has an aspect ratio of 6 and a span of 12 m. The wing loading is 900 N/m2 when flying at a speed of 40 m/s at sea level. Compute the induced drag for this wing. Also compute the downwash and the induced angle of attack (Note: at sea level, ?? = 1.23 kg/m3 ).

A finite wing with an area of 2.0 ft2, an aspect ratio of 7.0 and a span efficiency factor of 0.96 is mounted in a wind tunnel where the test section flow velocity is 110 ft/s at standard sea-level conditions. When the wing is pitched to a = -20, no lift is measured. When the wing is pitched to a = 10.00, a lift of 20 lbs is measured. Determine the lift curve slope for the airfoil (i.e., the infinite...

Consider an infinite wing with a NACA 1412 airfoil section and a chord length of 1.5 ft. The wing is at an angle of attack of 5° in an airflow velocity of 170 ft/s at standard sea-level conditions. Calculate the lift, drag, and moment about the quarter-chord per unit span. Refer to the Appendix graphs given below for the standard values. (Round the final answers to two decimal places.) 1)The lift per unit span is _______lb. 2)The drag per unit...

The RV-4, a single engine 2-seat light aircraft, has a span of 7.1 meters, an aspect ratio of 5.5, and a span efficiency factor of .65. If the aircraft is flying at a velocity of 260 km/hour at an altitude of 2,000 meters (a) What is the induced drag when the total weight is 5,700N?         (b) What is the induced drag with a velocity of 90 km/hour (the approximate stalling speed)?

Let’s say this airfoil was used in a specific airplane. This airplane is flying at 135 mph (60.4 m/s), has a wing area of 150 ft2 (13.94 m2), and flying at an angle of attack of 1º. How much lift will the wings generate? Use the lift equation that was discussed in Lecture 11, and give your answer in Newtons. Also, use an air density of 1.22 kg/m3 ** 1 degree of attack is 0.65.

A cargo plane has two wings and each wing has an area of 34.15 m2. The mass of the cargo plane is 9310 kg. When the plane is taking off, the speed of the air over the top of the wing v2 is 1.8 times air speed under the wing v1 (i.e. v2 = 1.8 v1). If v1 is the same as the speed of the plane, what is the minimum speed of the plane v1 to obtain enough lift...

A wing-body model is tested in a wind tunnel with a flow of 100 m/s at standard sea-level conditions. The wing area is 1.5 m2 and the mean aerodynamic chord length is 0.45 m. Measurements of lift force, L, and moment about the center of gravity, M CG are made using the wind tunnel force balance. B1(a) When the lift is zero, the moment about the center of gravity is measured to be, MCG = −12.4 Nm . At another...

A frequently quoted rule of thumb in aircraft design is that wings should produce about 1000 N of lift per square meter of wing. (The fact that a wing has a top and bottom surface does not double its area.) a)At takeoff the aircraft travels at 63.0 m/s, so that the air speed relative to the bottom of the wing is 63.0 m/s. Given the sea level density of air to be 1.29 kg/m3, how fast (in m/s) must it...
