Title: DISSECTION AND MODELING OF AEDC WIND TUNNEL 9 CONTROL LAW AND FACILITY DURING BLOW PHASE
Abstract:
This work presents the progress towards a mathematical modeling of the Arnold
Engineering Development Complex (AEDC) Wind Tunnel 9 control law during the blow
phase of a given tunnel run, composing of electrical analog physics, ideal gas control
volume physics, incompressible fluid mechanics, and force balance kinematics. Tunnel 9
does not currently have a well-defined process for developing control law parameters for a
new tunnel condition. The modeled control law is developed based on electrical schematics
and theoretical analog circuitry. The model is further refined by analyzing historical data
through a two-factor interaction analysis of several run-condition factors. The primary goal
of this work is to provide enhanced support to the Tunnel 9 engineers with the ability to
model different run conditions. Key facility measurements can be estimated, aiding in the
determination if proposed non-standard run conditions will meet or maintain the facility
capabilities, and if the facility can be operated under safe operating limits. The secondary
goal of this model is to progress toward a digitally controlled valve system to replace the
current analog system. Such changes may enable considerably more advantages in facility
(1) performance, (2) health monitoring, (3) maintainability, and (4) sustainment.
