Unformatted text preview: Lab 4 Design Problem Formulation Unified Engineering 4 Mar 06 Learning Objectives Measure and analyze prototype/baseline UE Competition airplane Formulate a suitable design space for a new wing Perform preliminary design and sizing studies. This will be a quantitative continuation of the exercise from Lab 1. Plane Vanilla Measurements for Redesign Baseline (reverse engineering) Measure the prototype Plane Vanilla airplane in order to determine S , b , W , Note the component weights given Measure the thickness/chord ratio of the root airfoil For wing weight and deection estimates, the pink foams approximate properties are: 3 2 . 0 lbm / ft 3 = 0 . 525 g / in 3 = 32 kg / m , E 2800 psi = 19 . 3 MPa The cross-sectional area of a typical airfoil is very nearly 2 A = 0 . 60 c t = 0 . 60 c which allows estimation of the wing volume and hence the wing weight. The weight of the remainder of the airplane can be assumed to be fixed for now....
