Project Overview

Timeline: Latest work (ongoing)

This project focuses on modifying a standard fixed-wing RC plane into a VTOL (Vertical Take-Off and Landing) aircraft. The conversion involves designing and integrating custom VTOL bars, new motor mounts, and a new powertrain. The flight control system will be upgraded with a Pixhawk to enable autonomous VTOL capabilities.

Technologies & Skills Demonstrated

  • Mechanical Design & CAD: Designing custom VTOL bars, motor mounts, and structural modifications to integrate VTOL functionality into an existing fixed-wing airframe.
  • Aircraft Conversion & Integration: Adapting an existing RC plane for new propulsion and control systems.
  • Flight Control Systems: Integrating and configuring a Pixhawk flight controller for VTOL operation.
  • Powertrain Design: Selecting and implementing new motors and power systems suitable for VTOL.

Project Development

Mechanical Design and Fabrication (Completed)

The initial phase involved the mechanical design of the VTOL conversion components. This included:

  • VTOL Bars: Custom bars designed to attach to the existing wing structure, providing mounting points for the vertical thrust motors.
  • Motor Mounts: Redesigned motor mounts to accommodate the new VTOL propulsion system.
  • Structural Reinforcement: Modifications to the airframe to handle the new stress loads from vertical thrust.

Electronics and Flight Control (Work in Progress)

This phase focuses on the integration of the electronics and the Pixhawk flight controller.

  • Pixhawk Integration: Setup and configuration of the Pixhawk for VTOL flight modes and transitions.
  • New Powertrain: Installation of new motors, ESCs, and propellers for vertical lift and forward flight.
  • Wiring and Sensors: Integration of all necessary sensors and wiring for the Pixhawk.

Challenges & Solutions (Planned)

  • Weight and Balance: Ensuring the converted aircraft maintains proper center of gravity and overall weight suitable for VTOL flight.
  • Aerodynamic Stability: Analyzing and mitigating potential aerodynamic instabilities during transition phases between vertical and horizontal flight.
  • Flight Control Tuning: Calibrating and tuning the Pixhawk for smooth and stable VTOL and fixed-wing flight characteristics.

Future Improvements (Planned)

  • Autonomous Flight Modes: Implementing advanced autonomous missions for VTOL operations.
  • Payload Integration: Designing a modular system for various payloads.
  • Real-time Telemetry: Setting up comprehensive telemetry for flight monitoring and data logging.
