Weapons Bay Cavity and Store Separation

Weapons Bay Cavity and Store Separation


  • This new unique course is essential for anyone interested in understanding cavity flow and stores separating from weapon bays
  • All students will receive an AIAA Certificate of Completion at the end of the course.

OVERVIEW
This unique course will discuss the physics of cavity flow and the challenges for modeling and simulation. A brief modern history of the use of weapons bays in military aircraft and the difficulties during a store separation event. The current research on studying store separation from weapons bay and techniques for prediction will be discussed.

LEARNING OBJECTIVES

  • Understand use of weapons bays on military aircraft
  • Understand the physics of cavity flow
  • Understand the store separation challenges
  • Understand predictive methods from analytical to computational
  • Learn about current research in understanding store separation from a weapon bay
  • Complete a series of exercises giving insight into cavity flow and store separation

AUDIENCE
Anyone interested in understanding cavity flow and stores separating from weapon bays. Past, present, and future application of modeling and simulation are drawn from the author’s 40 years researching and modeling cavity flow. Expect to learn basics of cavity flow physics along with several modeling techniques and challenges.

Bruce Jolly, CEO / Chief Technologist, Aero SME Consulting LLC. Retired as the US Air Force SEEK EAGLE Office (AFSEO) Principal Technical Advisor for Modeling and Simulation and selected by the US Air Force Academy (AFA) as a Visiting Scholar. Bruce joined the AFSEO in 1993 to insert Computation Fluid Dynamics (CFD) to be used in support of store compatibility. Over the next 32 years Bruce developed and proved the use of modeling and simulation to become the premier production CFD capability within the Air Force. Three generations of advanced CFD methods and many generations of high computing advancements later M&S supports every discipline within the SEEK EAGLE process. Recognized as a national subject matter expert in unsteady aerodynamics, CFD, and nuclear production technology, Bruce has supported many academic institutions, government laboratories, Von Karmon Institute, and the nation’s top security organizations for the past 25 years. He continually develops new methods for predicting the effects of the unsteady nature inside weapons cavities on store release. Over the past 20 years he has mentored AFA cadets’ summer research with AFSEO to over 40 cadets. Bruce is a sought-after lecturer having lectured internationally in Belgium, Sweden, Spain, Netherlands, and Canada as well as publishing over 30 technical papers presented nationally and internationally. He is an American Institute of Aeronautics and Astronautics Associate Fellow.
