The original requirement covered by this DEAFCON proposal was for the detailed design of two low speed half models, with a fully pressure plotted low sweep and high sweep wing respectively.

Removable and variable Leading Edge, Trailing Edge and Wing Tip devices were to be included, and the main element of innovation and learning for ARA would have been the integration of some form of Active Flow Control technology, which had not yet been defined.

Also included would be relevant design changes to an unknown, but existing, half fuselage FALCON model to enable appropriate integration of either wing configurations together with their relevant AFC actuators (recognising that these fuselage design modifications would need to be considered fully reversible).

However, prior to commencement of this programme, the scope and work content was changed quite considerably by the Topic Leader to comply with their final Specification document DGT-132940 Iss C Oct 2013.

This document presented the specification of the design of a single large scale half-model for testing in a pressurized low speed wind tunnel. Integration of any Active Flow technology was thus dropped at this stage, and the parts to design within DEAFCON became therefore:-

• A left-hand side modular wing with high aspect-ratio and low sweep
• A set of Body fairings to fit with the fuselage
• A left hand side cross-shaped HTP and its movable attachment fitting compatible with the former Vertical Tail
• A simplified main landing gear and its cavity

Project Context and Objectives:

The objectives within the framework of this overall project are now therefore:-

• Design of a pressure plotted left hand wing, with appropriate mounting to the WT test facility (ONERA) and relevant wing / fuselage fairings to mate with an existing fuselage
• Design of various Leading Edge (Kruger slat) devices
• Design of various Trailing Edge devices (conventional and Smart flap)
• Design of a left hand HTP to mate with an existing (modified) VTP
• Design of a simplified main landing gear
• Provide as Output Deliverables, the full CAD model and a final Stress Report
