2. AGENDA INTRODUCTION AIRCRAFT TERMINOLOGY THEORY OF FLIGHT
GLIDER DETAILS
HINTS
EXTRA--STARTING PLANS
MAKE A GLIDER

3. OBJECTIVE
TO DESIGN AND CONSTRUCT A BALSAWOOD GLIDER THAT WILL HAVE THE LONGEST DISTANCE (ms) OR FLIGHT TIME (hs) WHEN LAUNCHED FROM A HAND HELD CATAPULT.

4. MATERIALS BALSAWOOD. (why?) GLUE – ANY TYPE. MODELING CLAY. (purpose?)
PAINT, STICKERS, INK, AND MARKERS MAY BE USED FOR DECO OR ID. (Small areas only)

5. RULES NO READY MADE KITS. GLIDER WITH CLAY BALLAST
1:1 DRAWING WITH ISOMETRIC AND PLAN VIEWS- Computer Aided Design (CAD) AND HAND DRAWN PERMITTED (hs)
WING SPAN 10”min
(MS)

6. RULES- (CONT’D) NOSE HOOK FOR LAUNCHING GLIDER A MUST.
CATAPAULT WILL BE PROVIDED
LAUNCH RELEASE Ht=6 ft. max
3 LAUNCHES- 2 BEST COUNTED
MS- DISTANCE
HS-Time of flight

7. 4 FORCES OF FLIGHT

8. AXIS OF ROTATION

9. FLIGHT THEORY Newton’s 3 laws of Motion Inertia F=ma Action=Reaction
Bernoulli’s Law of fluid flow (1730’s)
K= ½ mv2 + PV + mgh
(m/V=ρ)
K= ½ rv2 + P + rgh

10. Tot. E=Kinetic E + pressure + potential E

11. Angle of Incidence

12. ANGLE OF ATTACK

14. DIHEDRALS

15. WHY DIHEDRALS?

16. GLIDER TAIL

17. TAIL FUNCTION HORIZONTAL STABILIZER-CONTROL PITCH- NOSE UP/NOSE DOWN
VERTICAL STABILIZER- CONTROL YAW- LEFT/RIGHT

18. STABILIZER SIZES OUTDOORS- HORIZONTAL-1/5 AREA OF WING
VERTICAL-1/3 TO 1/2 OF HORIZONTAL
INDOORS-
HORIZONTAL-1/6 TO 1/8 WING AREA
VERTICAL- 1/3 TO ½ OF HORIZONTAL

21. HINTS READ RULES THOROUGHLY. NO SQUARE EDGES.
STABILIZERS SMALL BUT NOT TO THE POINT OF INSTABILITY
CENTER OF GRAVITY OF FINISHED GLIDER IS 1/3 TO ½ FROM THE FRONT EDGE OF THE WING.
TAPERED BOOM.
OUTDOORS USE GLIDERS HEAVIER THAN 10 GRAMS.

22. MORE HINTS FUSELAGE LENGTH EQUAL TO OR SLIGHTLY LONGER THAN WINGSPAN
WING LOADING RATIO= GLIDER WEIGHT/WING AREA LOWER IS BETTER.
CIRCULAR FLIGHT PATTERN (ToF)
USE ‘TOOLS’ and ‘JIGS AND FIXTURES’ FOR DIHEDRALS, ETC.
TEST DIRECTION and ANGLE OF LAUNCH
USE ENGINEERING: DESIGN, BUILD,TEST
KEEP LOG BOOK AND RECORDS

28. FLIGHT PATH

29. TROUBLE SHOOTING
