Dynamics Engineer - Power & Propulsion

Mountain View, CA
Cora – Power and Propulsion
Full-time
Cora began as a dream. A self-piloting air taxi so personal and so simple it could take the trips we make everyday, the ones that define our lives, and bring them to the sky. We’ve been at work on Cora since 2010, tackling some of the biggest challenges in aviation. Today, that dream is one step closer. Join us in making that dream a reality.

We are seeking a Dynamics Engineer to join our team developing the propulsion systems of an electric aircraft.  You will work to develop lift fans and propellers in coordination with mechanical engineers, aerodynamics engineers, and structural analysts among others in a diverse and fast-paced team.  Your focus will be on building and validating dynamic models of propellers and lift fans for the purpose of optimizing, designing, and validating them. These dynamic models will include aerodynamic, structural, acoustic, and rotordynamic effects.  You will also be responsible for influencing the detailed design of these composite structures and mechanisms based on trade studies and optimization for load alleviation, ride quality, acoustic noise minimization, vibration reduction, and other desired characteristics.

Within 3 months you will:

    • Get to know the team, get to know the system
    • Learn some new analysis tools, get familiar with existing models
    • Propose improvements to development and analysis processes
    • Help perform some tests, collect and analyze the data

Within 6 months you will:

    • Become well versed in the dynamics models used to optimize and design new propellers and lift fans
    • Start a project using these models to design a clean sheet propeller or lift fan
    • Continue to validate and improve the dynamics model toolchain via comparison to measurements on working systems

Within 12 months you will:

    • Test hardware built using your dynamic models
    • Troubleshoot issues discovered during testing
    • Watch airplanes fly around making use of the hardware you designed
    • Support certification verification efforts
    • Continue to refine the modeling processes and toolchain of optimization and design of propellers and lift fans

Requirements:

    • BS, MS, or PhD in Mechanical, Aerospace, or Aeronautical Engineering
    • 5+ years of relevant work experience
    • Strong experience performing structural finite element analysis, preferably using NX Nastran or similar
    • Experience with aeromechanics tools such as Rotorcraft Comprehensive Analysis System (RCAS), CAMRAD, or equivalent
    • Knowledge of aircraft aeroelasticity, flutter analysis, structural dynamics, and loads analysis

Desired:

    • Knowledge of aerospace development best practices and standards
    • Knowledge of how to extract equivalent 1D beam models of complex 3D composite structures
    • Education or work experience in computational fluid dynamics
    • Experience with impact hammer testing and/or ground vibration testing (GVT) as a way of validating structural dynamics models at either the aircraft or component level
    • Technical writing skills for documenting loads, analysis results, model validation results, etc
    • Ability to analyze test data from aeroelastic and whirl flutter testing, comparing analytical results to experimental results
    • Demonstrated ability to go from concept to hardware in minimal time
    • Familiarity with MATLAB, Python or equivalent analysis tools
    • Experience with 3D modeling using NX, Solidworks or an equivalent CAD system
