WEIGHT ENGINEERING - AIRCRAFT ESTIMATION}, address = {Arlington, Texas}, abstract = {The history of Forward Swept Wing (FSW) design prior to the X-29A technology demonstrator is briefly recalled. The integration of the FSW with other elements of the demonstrator technology suite and the necessary interplay is described. A brief description or substantiation of the technology elements is included. The goals of the demonstrator program are reviewed and related to the design characteristics of the aircraft. Challenges facing the X-29A weight engineer are recounted, stressing weight-related development which includes: * Flight weight design of the FSW * Commonality with other aircraft * Weight evolution and meeting weight goals * Balance-critical aspects. The X-29A design is described from a weight and balance standpoint. Finally, future technologies are described and related to the existing technology suite. }, keywords = {11.

Advanced composite materials have opened the door to the use of forward swept wings in modern combat aircraft without excessive weight penalties.

After a brief discussion of the Nutcracker, a predecessor design, the paper presents a description of the unique configuration features of Design 698 rather than attempting to summarize the entire V/STOL program. Concepts discussed include the V/STOL nacelle, composites applications, engine sizing philosophy and the conformal radar, Weight statements and summaries of VTOL weight increments are included, }, keywords = {10.
