Dowty and Dream

SP2 R-R Geared Pusher Open Rotor

WP 2.2– Aero-acoustic Uninstalled - 22pm
Aero-acoustic and mechanical design & manufacture of rotor blades for R-R Rig 145 1/6th scale contra-rotating open rotor wind tunnel model
Refinement of Dowty contra-rotation performance and acoustic codes from results of Rig 145 low-speed & high-speed wind tunnel test results

SP3 SNECMA Direct-Drive Pusher Open Rotor

WP 3.1 Architecture and specifications – 11pm
Requirements/assessment of blade pitch-change mechanisms (PCM) for contra-rotating direct-drive open rotors
WP 3.2 – Open Rotor Design - 15pm + ARA subcontract 18pm
Development of classical flutter prediction code for contra-rotating open rotor &application to SNECMA/TsAGI wind-tunnel test rig model blades
Development of acoustic codes for contra-rotating open rotor & correlation with final SNECMA/TsAGI wind-tunnel rig test results
Concept studies and aero-acoustic design for advanced concept blades for final version of SNECMA/TsAGI wind-tunnel test rig.

Dowty aims to be a rotor blade and PCM design and manufacturing partner in an eventual open-rotor engine system, and DREAM will help develop tools and build partnerships.
