Introduction
Accounts for 80% – 90% of the aircraft’s climb drag.
Possible ways of reduction:
Increased span (Weight!)
Non planar concepts - Winglets, C wing, etc.
Thrust required curve for jet aircraft4/28
Objective To perform force (lift and drag) measurements on a
C-wing with a NACA 0012 profile at different angles of attack and compare the results obtained to those corresponding to a conventional plane rectangular wing.
To incorporate a C-wing into a remote controlled aircraft that can be maneuvered using the ailerons mounted on the C-wing.

Methodology To carry out CFD analyses on C wing geometries to finalize
the wind tunnel model based on optimum lift/drag ratio.
