Towards Generalized Certification of Slung Load Flight Envelopes

Authors / Details: Nicholas Motahari, Nandeesh Hiremath and Narayanan Komerath, Georgia Institute of Technology

Abstract
An alternative is sought to individual full-scale flight testing in order to certify the safe flight envelope for every combination of helicopter and slung load. The major uncertainty has been the difficulty in obtaining reliable aerodynamic load maps for use in dynamic simulation. The possibility of reliable certification based on an iterative process is discussed. Knowledge bases with parametric variation of canonical shapes are now feasible using the Continuous Rotation method. The test case of an empty engine canister is considered. An initial estimate of dynamics based on interpolation from a canonical knowledge base shows surprising accuracy, when the initial level of perturbation is adjusted. This is followed with scale model experimental data at different levels of detail, compared to estimates from knowledge of the geometry and inertia. It is shown that initial perturbation level changes the amplification path, but the eventual divergence speed is uncertain to less than 10 percent. Higher perturbation levels cause lower divergence speed as expected. Intermediate amplification behavior is also captured.
