INSPIRATION : WE WERE THINKING ABOUT INCREASING THE LIFT OF THE PLANE. BY INCREASING THE ANGLE OF ATTACK LIFT CAN BE INCREASED. SO WE THOUGHT THAT IF WE COULD MAKE MOVABLE SLATS THEN IT WILL SERVE OUR PURPOSE. HENCE WE DECIDED TO MAKE MOVABLE SLATS AND SEARCHED DIFFERENT MECHANISMS OF MOVABLE SLATS AND FINALLY DESIGNED OUR OWN MECHANISM!. WE ARE PLANNING IF WE CAN GET SOME STASICAL DATA USING SOME SENSORS, DURING ITS FLIGHT, SO AS TO SEE HOW PRACTICALLY SLATES ARE USEFUL. DETAILS ABOUT THE PLANE 1. WING : WE USED DESIGNFOIL SOFTWARE TO DECIDE THE AIRFOIL SHAPE OF THE WING. AIRFOIL IS SHAPE OF THE CROSS SECTION OF THE WING. WE CHOSE NACA 3415 WHERE # 3 IS MAX HEIGHT AS A PERCENTAGE OF CHORD. # 40 IS MAX CAMBER LOCATION AS A PERCENTAGE OF CHORD. AN AIRFOIL WHICH IS IS NOT SYMMETRIC IS CALLED CAMBER. # 15 IS MAX AIRFOIL THICKNESS AS A PERCENTAGE OF CHORD. CHORD LENGTH OF AIRFOIL : 25 cm TOTAL WING SPAN : 150 cm TOTAL AIRFOILS USED 14 WITH EQUAL SPACING. WE USED 3 mm BALSA FOR AIRFOILS.
WE CONNECTED ALL AIRFOILS THROUGH CONNECTING RODS. TWO CONNECTING RODS WERE THERE AT LEADING AND TRAILING EDGES AND ‘T’ & ‘I’ SHAPED CONNECTING RODS WITHIN THE AIRFOIL. WE MADE THE WINGS IN TWO PARTS AND THEN JOINT THE THEM BY LAYERS OF BALSA TO GIVE IT PROPER STRENGH. WE USED 6 SHEETS OF 3 mm BALSA TO MAKE THESE JOINTS.
