Abstract

This paper was presented at the Eighteenth National Conference of the S.A.W.E. May 18-21, 1959, Henry Grady Hotel, Atlanta Georgia.
With all the interest being expressed in the supersonic transport aircraft today, it is necessary that the Weight Engineer be cognizant of the effects of his performance and of his responsibility related to this type of aircraft. The purpose of this paper is to discuss some of the significant factors that can affect the Weight Engineer working on this aircraft. This paper provides an overview of some of current problems as well as some new problems to consider in evaluating the basic configuration for supersonic aircraft.
In summary the Weight Engineer’s role in the development of a supersonic transport is more important than ever before.
Five problems, some old, some new, are re-emphasized here:
(1) Temperature
(2) Structural efficiency
(3) Trim drag and pitch control
(4) Design airspeed
(5) Necessity of analytical weight estimating methods
In order to be fully effective, the Weight Engineer must be capable of presenting accurate evaluations upon which the basic airplane configuration can be developed.
