Aery Glider Design
Today’s Mission Requirements It is expected that students will: Describe the requirements for a glider to remain stable in flight. Design and construct a glider that meets the design requirements provided by the instructor. EQ: What factors affect lift and drag?
AERY Model Glider Software Design and analysis of simple gliders Center of gravity Neutral point determination Stabilizer and vertical tail volume coefficients Stabilizer angle of incidence determination Creation of plan for glider construction Prints dimensioned drawings of glider
Validity of Design Analysis Comparison of output to expected results Construction of test gliders Insufficient directional stability Required lateral balancing Center of gravity determination based on materials used

Will it Fly? Analysis AND it is stable Press F3 or under Analysis Once you get an AERY number AND it is stable Raise Hand
Building on a Single Sheet 90 cm or 36 inch Fuselage Wing Vertical Tail Horizontal Stabilizer Leave extra space at these locations if material allows 7.5 cm or 3 inch Notice the grain direction: Always spanwise! NOTE: Fuselage can be no LONGER than 35 cm or 12 inch Can be no WIDER than 2.5 cm or 1 inch
Once it is Stable Print your plans Exit to Lab room Safety Glasses Model Kit – for Knife Go to table with cutting board Ruler Balsa wood

Marking the Fuselage Wing Location Center of Gravity Neutral Point Cut for Length Wing Location Center of Gravity Neutral Point Horizontal Stabilizer Vertical Tail
Cut Out Pieces Cut the wing with extra span if material allows (see later note for reason) Cut out stabilizers Sand leading and trailing edges with minimal rounding
Finish Trailing Edge Trailing edge imperfections most often occur at wingtips If material allows, finish trailing edge then make final cuts for span and/or leading edge curvature
Shaping the Wing Profile Leading edge should have minimal rounding Trailing edge needs taper on top only Use sanding block and edge of a solid surface for uniform sanding
Adding the Wing Center the wing on the fuselage Glue it on straight and square to the fuselage . . . this is critical
Making a Strong Bond Avoid typical novice method of applying excessive glue on an edge and sticking material together Light bond with reinforcing fillets increases the glue surface area and bond strength
Add Horizontal Stabilizer One piece stabilizer Stronger Only possible if mounted somewhere away from vertical stabilizer Two piece stabilizer Weaker Mount anywhere else
Check Alignment Hold stabilizer on wedge Ensure from front or back that stabilizer is parallel to wing If not, sand wedge slightly and recheck
Vertical Stabilizer Side Mount Requires tail at a completely different location on fuselage from horizontal stabilizer Glue onto side of fuselage flush with bottom edge and front edge even with vertical tail mark Front Back Side of Fuselage VT VT Top View VT
Vertical Stabilizer Top Mount Can be used no matter where tail is located Draw line down center of fuselage top starting at vertical tail mark Glue on vertical tail straight and square Front Back Side of Fuselage VT Top View VT VT VT
Balance the Glider Place pencil on table top and put glider on top of it with center of gravity directly over pencil Add clay to nose until glider balances at the center of gravity
Balance the Glider Hold glider on fingertips placed at nose and tail Add clay to wingtips until glider balances at fuselage
