Question 1 (4 points) Saved Consider an aircraft in a steady and leveled flight, knowing that the airfoil 21.0 [m] wingspan travelling at 150.0 [m/s] if the air density is 0.525 [kg/m^3] and the circulation is 55.0 [m^2/s], calculate the total lift of weight? O equals to 4,330 [N/m) around 9,270 [kgf] Cannot be calculated because the weight of the plane is un-kown Total Lift is 90,900 [N]Question 2 (4 points) Saved An Aeronautical engineer is trying to design a new light aircraft, a total of a mass came as 1,150 [kg], and a wingspan of 10.0 [m], the small engine can run of a fixed speed of 150 [km/h], at this speed on a low altitude, a circulation equals to 50.0 [m^2/s], and the air density is 1.05 [kg/m^3]. Is the calculated total lift vs wingspan is sufficient? and why? No, the total lift = 960 [N/m], which is less than the total weight 1,150 [N] Yes, the total lift = 2190 [N/m], therefore the L' times wingspan = 21,900 N/m which is larger than the total weight of 19,620 [N] O Yes, the total lift = 2190 [N/m], therefore the L' times wingspan = 21900 N/m which is larger than the total weight of 11,281.5 [N] No, the total lift = 2190 [N/m], which is less than the total weight 11,281.5 [N]Question 3 (4 points) Saved Considering the Specific Fuel Consumption for an aircraft is 0.587 [Ibm/hr/lbf] leading to a fuel consumption rate of 12,680 [Ibm/hr], if a standard aviation jet fuel costs $3.50 [US/gallon], and has a density of 6.84 [Ibm/US gallon]. How much does fuel cost for each hour of level flight? $6490 per the round trip $6,490 per hour $6,490 per wingspan tank including reserved fuel $6,490 per one way tripQuestion 4 (6 points) Saved An aircraft has a specific fuel consumption SFC of 0.450 Ibm/hr per lbf of thrust. Assume this is a constant during normal steady cruise conditions. The thrust over this period is a constant 5,120 lbf. On a flight lasting 2.00 hours how much fuel is consumed by this aircraft? How much is the cost of fuel over this 2 hour flight? V 4600 Ibm of fuel 4600 Ibm of fuel per hour 2300 Ibm $2420 per hour $690 V $2420Question 5 (4 points) Saved At a cruising speed of 765 [mph], an aircraft consumed 2.73 x 10^4 [US gallons] of jet fuel (equivalent to 1.82 x 10^5 [Ibm]) while flying 8000 miles, it's two engines delivered a total thrust of 2.16 x 10^4 [Ibf]. What is the specific fuel consumption of the engines? 1.29 x 10^4 [Ibm of fuel]/[Ibf of thrust] 1.7 x 10^4 [Ibm of fuel]/[lbf of thrust] 0.598 [Ibm of fuel]/[Ibf of thrust] 0.806 [Ibm of fuel]/[Ibf of thrust]
