Fall Final Presentation November 30, 2004 MAVerick Solutions Todd Adkins Leroy Cohen Jr. Adam Hollrith Brian Moore

OVERVIEW OVERVIEW  Objectives  Wing Concepts  Deployment Mechanisms  Design Analysis  Cost Analysis  Current Work  Future Work

Objectives  Design and fabricate component technology that will provide a MAV the capability to collapse/fold all wing surfaces along the body of the fuselage  Assess current materials and technologies that will maximize subsystem performance and minimize size and weight (i.e. composites, plastic actuators)  Demonstrate final concept design at Eglin AFB  Furnish final report documenting project objective, approach, results, budget analysis for hardware used, and conclusions/recommendations

Specifications

Wing Concepts  Concept #1  Involves a pair of wings that fold along the sides of the fuselage  Pros - Compact design  Cons - Complicated deployment path - Multiple driving mechanisms - Two separately moving wings

Wing Concepts  Concept #2  Involves a one-piece, rotating wing  Pros - Simple deployment - Compact design - One rotating mechanism - One-piece wing design  Cons - Concentrated stress on single support - Possible interference with tail of MAV

Wing Concepts  Concept #3  Involves a bi-wing design that will allow for greater lift capabilities and improved glide slope  Pros - Greater lift capabilities than concept 2 - One-piece wing design - Central rotating mechanism  Cons - Possible wing interference - Greater weight

Wing Concepts  Concept #4  Comprised of a two-wing system that simply rotates into deployment  The wings overlap on the top of the vehicle fuselage while stowed  Pros - Simple and quick deployment - Compact design  Cons -Interference caused by overlapping wings - Two wing attachment points

Wing Concepts  Concept #5  Comprised of one central connection between the wings and the fuselage  Both wings will rotate from the same point  Pros -Central rotation point -Compact design -Simple and quick deployment  Cons -Interference from overlapping wings -Relatively more complex concentric shafts
