  3. Propulsion Engine : PW1521G High bypass turbo fan providing 17,000 lbs of thrust each. Hybrid Modifications : Electric motor integrated into the input shaft of the turbofan which is powered by batteries The purpose of the battery powered electric engines is to decrease the amount of fuel used while at cruising speeds. Our goal was to maintain a high level of efficiency throughout all stages of flight. Range for this aircraft is 1350nm and the endurance is 7.25hrs.

  4. Hybrid System The hybrid system contributes 3,293 lbs of thrust continuously. This equates to about 10% of overall thrust available when engines are at WOT. The electric motor is built into the output shaft of the gearbox. This placement keeps the motor clear of the bypass air, saves space, and keeps the drive structure contained and rotationally balanced. Two clutches are included on the shaft: one to disconnect the turbine, and the other to transfer power from the electric motor. Based on the batteries specifications, 10 batteries were selected to be used for flight and one additional battery for the electrical systems on board.

  10. Weight by Comparison Based on other aircraft with similar missions we can plot a graph of weight verses passengers, which is our payload. From this we can get an estimated empty weight of about 45,000 lbs. This is weight without engines. Using the spreadsheet given to us by Dr. Jacob we calculated an Empty weight of 42,000 with engines. The aircraft we benchmarked are made with a large percentage of aluminum, but like the Boeing 787, we designed our aircraft to have a much greater percentage of composite material which will cut down on weight. We expect that with the advancement of composites and other materials, by the year 2030 we will be able to reduce this weight by 20%.

  12. Additive Manufacturing Additive manufacturing is the official name for 3-d printing. The process eliminates wasted material, is faster than machining some parts, and is extremely cost effective. Because of the lack of wasted material, less man hours, and 24 hour work times, additive manufacturing can save huge amounts of money. In some calculations the savings were around 90%!
