Project Final Report – CUDBF April 30 th , 2009 ASEN 4028: Aerospace Senior Projects Figure 3: Flight Mission Lap Overview 2.2.1 Ground Mission: Assembly The ground mission begins with the aircraft, payloads, and transmitter fully restrained in the box. The box will be rotated on all sides to demonstrate restraint contents and will then be dropped from a height of 6 inches to show structural integrity. The team will then be timed on transitioning the stored aircraft to flight readiness with all payloads. The timed assembly factors into the Safety Complexity Factor (SCF) in Equation 2 below. = Equation 2: Ground Mission Score 2.2.2 Flight Mission 1: Ferry Flight The ferry flight begins with the aircraft placed on the runway with the empty centerline store attached. The aircraft will take-off, fly two laps, and land. This mission profile can be observed in Figure 4 below. Figure 4: Flight Mission 1 Profile The total flight time of the aircraft will be recorded and factored into the mission score. The time begins when the aircraft throttles up for take-off and ends when the aircraft passes over the starting line in the air. The mission score can be observed in Equation 3. 20
Project Final Report – CUDBF April 30 th , 2009 ASEN 4028: Aerospace Senior Projects 1 = Equation 3: Flight Mission 1 Score 2.2.3 Flight Mission 2: Surveillance Flight The surveillance flight begins with the aircraft placed on the runway with the full centerline store attached. The aircraft will take-off, fly four laps, and land. The mission profile can be seen below in Figure 5. Figure 5: Flight Mission 2 Profile The mission score for this flight is equal only to the aircraft SCF. Equation 4 below shows the flight mission score. 2 = Equation 4: Flight Mission 2 Score 2.2.4 Flight Mission 3: Store Release/Asymmetric Loads The store release flight begins with the aircraft on the runway with no payload attached and the rocket stores in the box. The time required to load the rocket stores to the aircraft will be used within the flight mission score. This relation can be seen in Equation 5 below. 3 = Equation 5: Flight Mission 3 Score The aircraft will take-off; fly one lap, then land. On the ground, the aircraft will taxi to a specified area and drop a store specified by the DBF officials. The aircraft will again take-off and repeat this process, finishing the mission by landing successfully after the fourth lap. This mission profile can be observed in Figure 6. 21
