摘要

The paper explains the UK approach to deriving ship helicopter operating limits (SHOLs). These are derived principally from the results of practical flight trials. The paper considers some of the important aspects of these flight trials, including trial prerequisites such as the derivation of performance and handling data. One of the main assessment tools are rating scales which are used to assess power and control margins, and pilot effort. A recent development is the Deck Interface Pilot Effort Scale (DIPES) which has been developed in cooperation with other nations for specific use in SHOL trials The practical aspects of trial conduct is reviewed together with aircraft and ship instrumentation requirements. Service use of the SHOLs is briefly discussed together with "mass correction" which caters for variations in ambient temperature and pressure. Developments in the field of modelling and simulation are discussed. Modelling of the dynamic interface (Dl) between an aircraft and ship, is a particularly demanding exercise, requiring integration of the various elements that make up the scenario. Helicopter aerodynamic models have to be combined with dynamic and visual ship descriptions to operate in a specified environment. The results of trials have shown that the various models can be integrated into a comprehensive simulation package and results are promising. Nevertheless, research in this field is relatively immature and certain areas of fidelity require further work. Finally possible future developments in this field are considered.
