Da’ Fuser Team Turbojet Diffuser Study Progress Report 3 Robby Swoish Mike Vostrizansky Ryan Wiltshire November 10, 2005

Progress Completed baseline pressure data measurements Completed baseline pressure data measurements Ran tests with two different mach numbersRan tests with two different mach numbers Cut diffuser model into two pieces so that the interior of the model may be accessed Cut diffuser model into two pieces so that the interior of the model may be accessed

Experimental Setup

Tests 5 and 6 Goal: Characterize initial pressure distribution in diffuser model for two mach numbers between.3 and.4 Goal: Characterize initial pressure distribution in diffuser model for two mach numbers between.3 and.4 Current Status: Data needs to be analyzed Current Status: Data needs to be analyzed

Cut Diffuser
