To solve the problem of finding the uniform speed of the aeroplane, we will follow these steps:Step 1: Understand the scenario The aeroplane is flying horizontally at a height of 1 km above the ground. It is observed at two dif
There is also a nose-down (negative) pitching moment, which has a more or less constant value when measured about the aerodynamic center of the airfoil. [From Stinton, D. (1983). “The Design of the Aeroplane,” Van Nostrand-Reinhold, Princeton, NJ.] Airfoil sections are designed for ...

A hummingbird is flying in such a way that it is initially moving vertically with a speed of 4.6 m/s and accelerating horizontally at 11 \; m/s^2. Assume the bird's acceleration remains constant. How much time is requir...
The aeroplane was used for research for imaging of marine and terrestrial ecosystems and for transmitting radio and TV signal as an “atmospheric satellite.” Eventually, Helios was destroyed in a crash in 2003. Longest flight duration achieved was over 17 h. 2.3.2 Solar Impulse Solar Impulse ...
Assuming that the aeroplane is now flying at substantially sea level, the air thrust is then at the maximum and the blade has moved forwardly about the surface of a cone, to assume the forwardmost position which will impart to. the blade the minimum pitch. During this action of the blade...
After flying at an altitude of 500 meters, a helicopter starts to descend when its ground distance from the landing pad is 11 kilometers. What is the angle of depression for this part of the flight? An aeroplane takes off over a flat...
in three days smashing three reserve regiments and at the greatest point advancing 235 miles east. On the 6th October a drive to the south started which took key White ports and captured a huge quantity of equipment including 600 trucks of British-supplied ammunition and an aeroplane. This was...
An aeroplane flying horiontally 1 km above the ground is observed at an elevation of 60^@ and after 10 seconds the elevation is observed to be 30^@. The unifo
A light aeroplane starts its take off from rest and accelerates at 1.25 m/s2. It suddenly suffers an engine failure and decelerates back to a halt at 1.875 m/s2, coming to rest after a total distance of 150 m along the runway. Find the maximum velocity reached, and the total time take...
