STC supports the US Army's Technology Development Directorate (TDD) located at 
the NASA Ames Research Center at Moffett Field, CA. Much of this support 
involves the development and application of modeling and simulation tools for 
rotorcraft aerodynamics and structural dynamics in Army acquisition-related 
programs such as Future Vertical Lift. These modeling and simulation activities 
aim to improve performance, reduce risk, and enhance safety for Army rotorcraft. 
The Army’s primary computational fluid dynamics tool for high-fidelity rotary-
wing aeromechanics simulations is called “Helios.” The Helios software consists 
of a number of multi-disciplinary computational modules that connect through a 
lightweight and object-oriented Python language infrastructure. Helios can 
analyze multiple-rotor, multiple-rotor and fuselage combinations with intended 
analysis applications for new Army rotorcraft acquisition activities that are 
part of the Army’s Future Vertical Lift (FVL) program.


Responsibilities
The Helios development plan calls for annual software releases with major 
upgrades and improvements to individual software modules with each new release. 
This position requires the formulation, development, and testing of new and 
improved software modules for Helios. These new software improvements will 
involve new and improved, solution algorithms for existing flow solvers, new 
gridding strategies and flow solvers, new modeling capabilities such as 
rotorcraft maneuver, and new strategies for improved parallel scalability. This 
requirement requires creativity and vision for developing, implementing, and 
testing new capabilities that are targeted for future Helios software releases.

Job Requirements
The successful candidate should have substantial experience and expertise in the 
development and application of high-fidelity computational fluid dynamics 
software and high-performance parallel computing. Experience in multi-
disciplinary fluid and structural dynamics problems related to rotorcraft is 
also a plus. M.S. degree in Mechanical or Aerospace Engineering is required, the 
Ph.D. is preferred. This position is open to US citizens and US permanent 
residents.
