Wind tunnel testing for Installed loads 2

it sounds to me like you want to find the aero loads on external stores ? i think that means that the store attmt to the wing needs to be strain gauged, maybe you can rig a small force balance, but that doesn't sound too practical to me. there shuld be lots of info out there on this, it is a pretty common subject. there's also CFD.

In addition to direct measurements of store loads in a wind-tunnel (using strain gages as suggested by RB1957), I recommend you navigate to the ASSIST website, and download a copy of MIL-H-8591H entitled "Airborne Stores, Suspension Equipment and Aircraft-Store Interface (Carriage Phase)"
This document has a wealth of information in the appendices on calculating store loads. Maximum store loads experienced(in flight) includes the aerodynamic loads you are trying to measure, the inertia loads resulting from aircraft accelerations, and local loads like preloads on sway braces and hooks - depending on the bomb-rack/pylon selected.
