Weight Engineering - Aircraft Estimation %X In determining unit and operating costs for advanced aircraft,it has been found that by having first-order weight and performance approximations for the aircraft systems and structural components, a step increase in cost prediction accuracy results. This paper presents first-order approximation equations for these systems and components. These equations were developed from data for most current jet transports,and they have been ordered to use a minimum number of performance parameters such as aircraft style, number of passengers, empty and gross weight, cargo load, and operating range. A NASA Ames Research Center aircraft cost program has been used to compare calculated and actual weights for the same aircraft. Good aircraft cost correlation is shown to exist between calculated first-order and actual aircraft weight data. %B 33rd Annual Conference, Fort Worth, Texas, May 6-8 %I Society of Allied Weight Engineers, Inc. %C Fort Worth, Texas %P 17 %8 5/6/74 %G eng %U https://www.sawe.org/papers/1024/buy %9 11.0.
