In our question, we are to consider an airplane pattern after the beachcraft bonanza v -tailed single -engine light private airplane.
00:08
Now, the characteristics of the airplane are as follows.
00:11
Its aspect ratio being equal to 6 .2, wing area of 181 feet square, oswald efficiency factor of 0 .91, weight 3 ,000 pounds, and 0 lift drag coefficient of 0 .07.
00:29
The airplane is powered by a single piston engine of 345 horsepower maximum at sea level.
00:38
Assuming that the power of the engine is proportional to free steam density, we need to calculate the range and endurance at standard sea level.
00:49
Now first let us choose a velocity, say v infinity being equal to 150 feet per second.
00:57
That is the given trial value.
00:59
For the same we have q infinity to be equal to half, row infinity, v infinity, the whole square.
01:10
Substituting the value we get multiplied by 0 .002377, multiplied by 150 the whole square, which is equal to 26 .7415 pound per feet square.
01:28
We get c of l being equal to u infinity multiplied by s which is equal to divided by 26 .741 into 181 which gives us c of l being equal to 0 .62 now c of d will be equal to d comma o plus c of l the whole square divided by pi dot e dot aspect ratio which will be equal to 0 .027 plus 0 .62 the whole square divided by pi into 0 .91 multiplied by 6 .2 which gives us the day being equal to 0 .0487.
02:20
Therefore the thrust required can thus be calculated as w divided by c l by c l by c cd which will be equal to 3 ,000 .62 divided by 0 .0487 which is equal to 235 .645 pounds.
02:45
This gives us the power required being equal to t of r multiplied by v infinity which is equal to 235 .645 pounds multiplied by 1 .5 pounds multiplied by 1 .5...
