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 μm and 14 μm. 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).

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.
Mr. Bartell (BS US Air Force Academy, MS University of Arizona Optical Sciences Center) is currently a Research Physicist with the Air Force Institute of Technology’s Center for Directed Energy where he leads the development of the High Energy Laser End-to-End Operational Simulation (HELEEOS) model. Prior to his affiliation with AFIT Mr Bartell was previously employed with Veridian Systems Division (formerly ERIM) where he supported several state-of-the-art tactical and strategic reconnaissance research and development programs. He led the development of HySIM, the Hyperspectral System Image Model. Earlier, as a senior engineer with LaserMike Inc. Mr. Bartell was responsible for product specification development, comprehensive electro-optical design, and prototype development and testing for new lines of laser scanners. Mr. Bartell served as an Instructor Weapons Systems Officer in the F-111D and F-111F from 1980 to 1986.
Steven T. Fiorino, Research Associate Professor of Atmospheric Physics (BS, MS, Ohio State University; MMOAS, Air Command and Staff College; BS, PhD, Florida State University). Dr Fiorino's research experience includes microwave remote sensing, evaluating uncertainty in high-energy laser engagement due to atmospheric effects, and improving microphysical characterizations for nuclear fallout, transport, and dispersion.
Mr. Krizo is currently a research engineer in the Center for Directed Energy and the lead programmer for the HELEEOS project which he has worked on since 2004. He oversees the development of the model and the incorporation of new capabilities into HELEEOS. He received a BSEE in 2005 from Cedarville University and an MSEE from the University of Dayton in 2008.
