Welcome to my portfolio. Here, I present a detailed exploration of my pet project developing an autonomous drone — working title: “Stingray”. The airframe is primarily made from PLA, chosen for its ease of printing and rigidity, with critical areas reinforced with TPU to improve shock absorption.

The drone is controlled by a Matek F411-WTE flight controller running INAV 7.0. Key components include the FS-iA6B 2.4GHz iBUS Receiver for reliable communication, a 900MHz Telemetry Radio Module for long-range data transfer, and a HGLRC M100 UBLOX GPS for navigation.

It is powered by an EMAX ECO II 2207 – 1700Kv Brushless Motor and a 2S Lithium-Polymer battery, balancing power with efficiency. This portfolio provides an in-depth look at the integration of these technologies into a functional and versatile drone design.

Explore the sections below for more insights into this project.

I started developing a secondary design, tentatively called “Sparrow” — a simplified, streamlined version of the Stingray. In its CAD design, I used more advanced surface modeling techniques, resulting in the smooth, continuous curvature shown below.

Can’t have an aeronautics project without a little CFD…

Nice to see the pressure differential validate the airfoil selection (NACA 4410).
