HELEEOS Short Course
Degree Type: Professional Continuing Education
This short course provides a preview of Version 3 of the High Energy Laser End to End Operational Simulation (HELEEOS) scaling law engagement model developed by the Air Force Institute of Technology (AFIT) Center for Directed Energy. HELEEOS has been developed, under sponsorship of the HEL Joint Technology Office, to support a broad range of analyses applicable to the operational requirements of all the military services. HEL performance for an example scenario will be estimated in class using the model.
HELEEOS uses the scaling laws of the Scaling the High energy laser And Relay Engagements (SHaRE) toolbox. SHaRE is anchored to the respected wave optics code WaveTrain and all significant degradation effects, including thermal blooming due to molecular and aerosol absorption, scattering extinction, and optical turbulence, are represented in the model. The HELEEOS model enables the evaluation of uncertainty in low-altitude high energy laser engagements due to all major low altitude atmospheric effects to include physically-based representations of water clouds, fog, light rain, and aerosols. HELEEOS can be used to evaluate spatial, temporal, diurnal and seasonal uncertainties due to atmospheric effects on estimates of high energy laser system effectiveness. The model simulates HELs operating at a number of wavelengths between 0.355 &mu m and 14 &mu m. A number of operationally oriented metrics are available, including effective range and required dwell time. Worldwide seasonal, diurnal, and geographical spatial-temporal variability in key climatological parameters is organized into probability density function databases in HELEEOS using a variety of recently available resources to include the Extreme and Percentile Environmental Reference Tables (ExPERT) for 408 sites worldwide, the Surface Marine Gridded Climatology database which providing coverage over all ocean areas, the Master Database for Optical Turbulence Research in Support of the Airborne Laser, and the Global Aerosol Data Set (GADS). CEUs awarded: 0.35
This course is designed to show new users how to begin using HELEEOS. By the end of the course, attendees will be able to effectively and efficiently use both models.
This course will be appropriate for anyone who has the need to simulate High Energy Laser system performance. An undergraduate degree in science or engineering is recommended.
