“…Unsucessful attempts were made at extending the application of the subsonic panel code VSAERO to the calculation of transonic flow around a wing-pylon-nacelle configuration by Lord and Zysman [66] and over several wing-pylon combinations by Carlson and Lamb [48]. Recently, Madson et al [68] employed a transonic full-potential approach to compute the flowfield around a wing-pylon-finned store geometry at Mach numbers of 0.95 and 1.20. The results were compared to wind tunnel measurements and to calculations using Euler and thin-layer Navier-Stokes approaches.…”

In transonic flow, the aerodynamic interference that occurs on a strut-braced wing airplane, pylons, and other applications is significant. The purpose of this work is to provide relationships to estimate the interference drag of wing-strut, wing-pylon, and wing-body ar- his office, leaving with more answers than questions. I also appreciate the fact that he has always had a friendly attitude towards me. I have enjoyed interacting with Dr. Kapania, whose cheerful attitude and perpective on life and research is very similar to mine. I would like to acknowledge the contribution of Dr. Grossman to the team in the field of numerical calculations and his desire of improving the life of the graduate students by forming the Graduate Advisory Committee. Dr. Raj deserves a lot of thanks for providing me with useful advice throughout this project despite his busy schedule. I appreciate the fact that he has always been interested in knowing more about the evolution of my research work and career. The "virtual" presence of Dr. Haftka during our weekly meetings has been very beneficial because of his ability to foresee difficulties and to get the team members to not lose sight of the big picture.

“…The first of these was for the wing/pylon/finned-store, which occurred in Hilton Head, SC in the summer of 1992. One of the important results from this initial conference was the discovery that full potential methods (2) gave answers equivalent to those provided by an Euler (3) code for the wing lower surface in the presence of the store.…”

Any time a new aircraft is introduced into service, or an old aircraft undergoes substantial modifications or needs to be certified to carry and employ new stores, the store separation engineer is faced with a decision about how much effort will be required to provide an airworthiness certification for the aircraft and stores. Generally, there are three approaches that have been used: wind-tunnel testing, computational fluid dynamics (CFD) analyses and flight testing. During the past twenty years there have been considerable advances in all three areas. In particular, there has been a considerable improvement in the speed and validity of CFD results for store separation. The Holy Grail of CFD has long been the reduction/replacement of wind-tunnel testing. This would mean in store separation the ability to go from a CFD calculation to flight testing at the end point. The paper will describe how this was achieved for the F/A-18C/Litening pod program.

This paper explores the advantages of using computational fluid dynamics (CFD) to predict store trajectories. The focus will be on comparing CFD based store separation predictions with experimental data derived from wind tunnel and flight tests. Of particular interest are the abilities of new engineers to use various CFD packages to accurately predict store captive loads and separation forces, moments and trajectories in support of real stores clearance processes. The first phase made use of existing CF-18 Aircraft/MK-83 trajectory data from ongoing flight-tests by the Canadian Airforce.
