1. Goal of Project • Establishes the general concept, What it should do and how it will be used • Product is usually a set of initial requirements and expectations for cost and schedule 3

2. Schedule 4

3. Members Chief engineer [강 창 호] Air vehicle engineer [강 애 량] Subsystem engineer [최 재 영] Electric engineer [오 혜 영] performance analysis engineer [김 창 규] weight engineer [이 홍 일] 6

4. 1 Requirement Analysis Tier II: Medium altitude, long endurance Multi-Mission ISR Intelligence, Surveillance, Reconnaissance (ISR) 7

• Interdiction and armed reconnaissance against critical, perishable targets • Reconnaissance, surveillance and target acquisition in support of the Joint Forces commander • Reconnaissance is now accomplished with: – Persistent airborne platform – Day and night streaming video – Synthetic aperture radar to image through clouds – Near instantaneous distribution world wide 8

• Long Endurance Armed Reconnaissance – 30~50 hr flight times – Camera and radar sensors to detect – Precision weapons to destroy • To make it routine – The pilot/crew had to come out of the airplane – The airplane had to be reliable enough to run for 30 – 50 hr per flight – A control scheme had to be developed in order to fly the airplane anywhere – Unique distribution and reception systems HG 620 TJC 9

4. 2 Air Vehicle analysis 10

Mid Wing • Provides lowest drag • Some ground clearance benefits of the high wing (Possible under wing stores) • Advantages in aerodynamic maneuver • Structural carry-though presents a weight increase Y-tail • V-tail is used only pitch control • the third vertical stabilizer is used yaw control 11

Parametric analysis Using Excel spread sheet 32

5. Conclusion MQ 9 are well suited for precision weapons delivery – Designs allow easy mission role expansion – Man-in-the-loop allows for positive control of weapons employment – Satellite control and persistence allows weapons to be in the right place at the right time to engage time sensitive targets • MQ 9 will bring significant additional capability to the fight. 36
