Autonomous Flight System Overview
Navigation Guidance Control Determination of Attitude & Location
Determination of Flight Path
Execution of Control Logic
Why Autonomous Flight? • Enhanced payload capabilities • Creating a research platform
Chosen Autopilot: Cloud Cap Tech Piccolo SL
Remote controlled takeoff, autonomous flight, remote
controlled landing
10
Systems Engineering Process
Driving Question: How do we design for on-time autopilot deployment and successful flights? Analysis and Simulation: • Plane model (AVL, XFOIL) • Engine models • Create flight plans • Software in the Loop
Risk Mitigation: • Train pilot in software model • Verify plane model with R/C piloting • Prepare flight anomaly responses

Design, build and test a hybrid propulsion system to be integrated into the Hyperion blended wing-body aircraft
Hybrid Gas-Electric Propulsion
Coaxial drive: Increased efficiency
Multiple operation modes
Focus: Reliable Operations
Electric Motor & Gearbox
Project Testing Process
15
Novel Hybrid Propulsion System
• Tested on RASCAL aircraft
- Proven Aerodynamics
- More stable, easier to fly
Hyperion 2.0 Flight Testing
• Initial Testing w/ Electric Motor
- New wing design
- Safer testing approach
16
Prototype Testing
Purpose of Half-Scale Prototypes • Prove aerodynamic design
• Understand dynamic behavior
• Cheap and proven test method
