Development of a Cockpit-Pilot Model for Thermal Comfort Optimization During Long-Mission Flight

Abstract

The thermal comfort of a pilot is of crucial importance to maintain a high level of concentration and awareness during the entire flight mission. In this work a model for the thermal environment of the cockpit is developed and used as provider of input parameters to a thermoregulatory model, adopted from the literature, of a human. The cockpit-pilot model will be used to investigate and improve the thermal comfort for the pilot, particularly during longer flight missions.In the cockpit model a combination of lumped systems and finite difference calculations is used to obtain input parameters, which are provided to the pilot model. The body, with clothes, is divided into 16 segments and a finite difference method is used to determine the temperature distribution within these. Several physiological mechanisms are included in the model.Simulations with different boundary conditions show that the models work properly even for longer missions.

Realizing Interoperability between MBSE Domains in Aircraft System Development

“…However, as visualized in Figure 1, combining the two standards enables interoperability between all the considered M&S application levels of abstraction. The industrial feasibility and strengths of the FMI and SSP standards have been demonstrated in numerous publications within the aeronautical industry [26][27][28] and the automotive industry [29]. Furthermore, initiatives related to managing SSP and FMI compliant digital artifacts throughout a product life cycle is ongoing in both industry and academia.…”

OMSimulator - Integrated FMI and TLM-based Co-simulation with Composite Model Editing and SSP

“…The specified mass flows, temperatures, and pressures are achieved via a total of five modelled motorized valves controlled by a modelled software, denoted ECS Control in the figure. The included consumers are a thermoregulatory cockpit model, described in detail by Schminder et al in (Schminder et al, 2016), along with two simple place-holder consumers representing subsystems requiring air cooling and/or pressurization. The cockpit model provides necessary inputs to the included pilot comfort model which incorporates numerous wellestablished comfort measures into the simulation, such as the Fighter Index of Thermal Stress (Nunneley and Stibley, 1979).…”
