The Aero2 cargo drone developed by Dufour Aerospace represents a new approach to transporting critical supplies across long distances. Designed as a hybrid-electric VTOL aircraft, the drone combines helicopter-like vertical takeoff with the efficiency and speed of fixed-wing aircraft.

The concept addresses a growing global challenge: delivering medical supplies, emergency equipment, and time-sensitive cargo to locations where conventional aviation is expensive or impractical.

Helicopters and airplanes can perform these tasks, but they require pilots, large operating budgets, and complex infrastructure. In remote regions or emergency situations, these limitations can significantly slow response times.

Dufour Aerospace believes autonomous cargo drones could provide a safer, more efficient alternative.

The Engineering Challenge Behind Advanced Drones

Designing such aircraft is far from simple.

Modern aerospace systems must integrate multiple engineering domains simultaneously:

• aerodynamics
• propulsion systems
• flight control software
• structural engineering
• safety certification requirements

As Dufour Aerospace expanded its development efforts, the company faced a common challenge in high-tech engineering organizations: managing increasingly complex product development workflows.

Early in the company’s growth, design data was managed using manual processes and disconnected tools.

Engineering teams relied on spreadsheets, manual exports, and fragmented communication between design and manufacturing departments. As projects grew more sophisticated, these workflows became increasingly inefficient.

According to CEO Sascha Hardegger, coordinating multiple engineering disciplines required a more integrated system.

Moving to Cloud-Native Engineering

To streamline its development process, Dufour Aerospace adopted Onshape, PTC’s cloud-native CAD and product data management platform, together with Arena PLM for product lifecycle management.

Unlike traditional CAD tools that rely on local installations and file-based workflows, Onshape operates entirely in the cloud.

This approach allows engineers to collaborate in real time on the same models and design data from anywhere in the world.

For a company developing complex aerospace platforms, this capability is particularly valuable.

Aircraft design requires constant iteration between teams responsible for structures, electronics, software, and manufacturing. Real-time collaboration reduces the delays that often occur when engineers work with separate file versions.

Faster Development and Lower Costs

Since implementing Onshape and Arena, Dufour Aerospace has reported significant improvements in efficiency and cost control.

Key results include:

• Approximately $100,000 saved annually in CAD licensing and infrastructure costs
• 50% reduction in manufacturing data requests thanks to improved design transparency
• Up to eight hours saved per engineering release through automated design handoffs

These improvements allow engineering teams to focus more on innovation rather than administrative processes.

Real-time collaboration also enables faster iteration of complex systems such as hybrid propulsion architectures and rotor configurations.

The Aero2 Hybrid VTOL Concept

The Aero2 drone itself is designed to fill a gap between helicopters and traditional cargo aircraft.

Its hybrid-electric architecture enables vertical takeoff and landing while transitioning into efficient forward flight for long-distance travel.

This combination allows the aircraft to:

• operate without traditional runways
• carry substantial payloads
• travel hundreds of kilometers
• maintain lower operational costs than helicopters

Such capabilities make it particularly suitable for logistics missions in remote regions, disaster zones, and offshore operations.

The Future of Autonomous Cargo Aviation

As global logistics networks evolve, autonomous aircraft are expected to play an increasingly important role.

Cargo drones like the Aero2 could eventually support applications such as:

• medical supply delivery to remote communities
• emergency logistics during natural disasters
• industrial transport to offshore platforms
• military and humanitarian supply missions

For companies developing such systems, engineering efficiency is critical.

Modern aerospace platforms require thousands of components, complex certification processes, and tight integration between hardware and software systems.

By adopting cloud-based engineering platforms like Onshape and Arena, Dufour Aerospace aims to accelerate innovation while maintaining the high reliability standards required in aviation.

In the emerging world of autonomous cargo aviation, the ability to design faster may become just as important as the aircraft themselves.
