Clearance Analysis
In rough seas, helicopters can move significantly, resulting in potential safety issues and airframe damage.
Using OnDeck, AVT can determine the dynamic clearance of a helicopter for a range of conditions. Any number of critical points can be considered. SHOL limits, an estimate of sea state capability and an estimate of the likely collisions per hour can be derived.
Simulation mitigates the risk of structural interference and enables operators and ship builders to optimise hangar space and multiple helicopter separation. It also helps define maintenance procedures. Shown above is the clearance of NFH90 on FFH as part of Air9000 Phase 8
Clearance analysis can be conducted with applied lashings or restraint systems like RAST, ASIST, Decklock or the MacTaggart Scott TRIGON system. Shown above is a typical Estimation of Collision Events per Hour
AVT has conducted this analysis for the Seahawk, Seasprite, MRH90 and NFH90 on a number of ships. Using the MHA system AVT can fully validate the predicted response of the helicopter. Shown is a Seaprite with a low slung radome.
