CANARD PLANE PROJECT

Aim :- To build a RC(Remote Controlled) Canard
Plane.
What is canard plane? 
Canard is an airframe configuration of fixed wing aircraft in which the forward surface is smaller than the rearward, the former being known as the "canard", while the latter is the main wing. In contrast a conventional aircraft has a small horizontal stabilizer behind the main wing.
Canard designs fall into two main classes:-
a) Lifting canard:- In this configuration, the weight of the aircraft is shared between the main wing and the canard wing
b) Control canard:- most of the weight of the aircraft is carried by the main wing and the canard wing is used primarily for longitudinal control during maneuvering. The pros and cons of the canard versus conventional configurations are numerous and complex, and it is impossible to say which is superior without considering a specific design application.

Various Parameters involved in the design of Canard Plane:-

1) Both canard and main wings should be of high aspect ratio. The canard should have higher aspect ratio than the main wings.
2) The airfoil section of the canard wings should stall before the main wings.
3) The area of the canard wings should be 20% to 40% of the main wings.
4) Keep the distance between the canard wings and the main wings as long as possible.
5) The balance or the centre of gravity should be just ahead of the main wings.

2) Δ wings: 6
Wing area:
1) Canard wings: 45 sq inches
2) Δ wings: 216 sq inches

Materials required:
 Corofoam
 Styrofoam
 Biofoam
 Carbon rods
 Balsa wood
 Servo motors
 Brushless motor
 Push rods
 ESC
 Battery
 Reciever
 Polythene sheet
 Glueing material-cellotape, gluegun, bondtite, bondquick, etc

PROCEDURE:-
 Construction of fuselage using coroplast
 Designing and giving shape to the fuselage nose made up of Styrofoam.
 Construction of canard wings using biofoam.
 Construction of main wings using biofoam. They are delta shaped wings and require fine tapering to reduce air drag.
 Construction of ailerons and giving them proper airfoil shape.
 Strengthening of the main wings using carbon rod.
 Making of the vertical stabilizer and rudder using thick corofoam.
 Covering the main wings with tight polythene sheet to provide airfoil shape.
 Mounting of canard wings, main wings and vertical stabilizer.
 Mounting of the servo motors on the wings, rudder and fuselage.
 Mounting the main brushless motor at the back to provide thrust to the plane.
 Placing the ESC , battery and receiver.
