DESIGNED AROUND THE DELIVERY
Carry what matters.
Keep the noise down.
We’re developing a cargo drone with a focused purpose: move useful payloads over short distances while reducing the sound of flight. From rotor selection to the payload compartment, every decision starts with that mission.

What is Valdeira-1?+
Valdeira-1 is the cargo drone in development at Eversteel Technologies, a student team focused on quieter flight. Development currently covers aircraft configuration, propulsion, aerodynamics, payload integration and battery sizing.
How much can it carry?+
The design brief targets a 5 kg payload and a cargo envelope of 0.50 × 0.50 × 0.50 m. These remain design requirements to be demonstrated through testing.
How quiet is it?+
The acoustic objective is 50 dB(A), with hover measurement 5 m vertically below the aircraft. Sound performance has not yet been measured. Testing will cover hover, cruise, take-off and landing, with both loaded and empty aircraft.
How does a delivery work?+
The planned sequence is a 2 km outbound flight with cargo, manual landing on a flat 3 × 3 m area, stopping the motors, unloading and returning empty over 2 km.
Is the aircraft ready to fly?+
The project is in conceptual design. The physical prototype, final hardware choices and flight-test programme are still ahead. The images show renders of the current Valdeira-1 design.
