An aircraft has a steady rate of climb of 300 m/s at sea level and 150 m/s at 2500 m altitude.What will be the time taken for this aircraft to climb from 600 m altitude to 3100 m altitude?
Consider an airplane in an accelerated climb. At a given instant in this climb, the specific excess power is 120 ft/s
Consider an airplane flying at 620 mi/h at 35,000 ft. Calculate its energy height.
For a turbojet-powered airplane with the altitude variation of thrust given by Eq. (3.19), show that as the altitude increases, the maximum velocity decreases.
The BD-5J is equipped with plain flaps. The airfoil section at the wing root is an NACA 64-212, and interestingly enough, it has a thicker section at the tip, an NACA 64-218.
For the BD-5J, calculate (a) The maximum value of CL/CD (b) The maximum value of CL^(1/ 2) /CD
Consider a wing with a thin, symmetric airfoil section in a Mach 2 airflow at an angle of attack of 1.5°. Calculate the lift coefficient
What is a loitering munition ?
How urban air mobility work?
The velocity at a point on the wing placed in a wind tunnel is \(251 m/s\). The pressure and temperature of the test section is \(1\,atm\) and \(285\,K\). If the velocity of the flow in the test section is \(235\;m/s\), find the pressure coefficient at the point.
