Question

A jet aircraft has a thrust specific fuel consumption of 0.6 lbs/t-ℎr, an l/d of 11.2 , and a starting total weight of 92,730lbs. It loiters in the air for 1ℎlbs, burning fuel during this time. While the aircraft was loitering, how much total fuel was burned? Give your answer in Ibs.The lift over drag coefficient is used in finding the solution

Answer 1

The amount of fuel burned during the aircraft's loitering time can be calculated by multiplying the thrust specific fuel consumption (TSFC) by the total weight.

Step-by-step explanation:

To calculate the amount of fuel burned during the loitering time, we first need to calculate the fuel flow rate. The thrust specific fuel consumption (TSFC) is given as 0.6 lbs/t-hr, which means the aircraft burns 0.6 pounds of fuel per hour for every 1 pound of thrust produced. The starting total weight of the aircraft is 92,730 lbs. Since the aircraft loiters for 1 hour, the fuel burned during this time can be calculated by multiplying the TSFC by the total weight:

Fuel burned = TSFC x Total weight = 0.6 lbs/t-hr x 92,730 lbs = 55,638 lbs

Therefore, during the loitering time, the aircraft burned a total of 55,638 pounds of fuel.
