Lightweight Construction for Highly Efficient Drones

Drawing on years of experience in the aerospace engineering industry, Connova Group has also been active in the field of professional drones for several years. As with all aircraft, lightweight construction plays a crucial role in unmanned aerial vehicles as well.

Every kilogram saved in structural weight translates to more payload, more fuel, or both. Our expertise in the development and manufacture of lightweight structural components ensures the successful implementation of lightweight construction projects for highly efficient drones.

Why Use Fiber-Reinforced Composites for UAVs and Drones?

For unmanned aerial vehicles, the structural weight determines the key performance metrics: payload, range, and flight duration. Carbon-fiber-reinforced plastic (CFRP) offers a stiffness-to-strength-to-weight ratio that cannot be achieved with aluminum or titanium. This is precisely why fiber composites are the standard material for demanding UAV structures.

Lightweight, high rigidity

CFRP structures significantly reduce structural weight compared to metal while maintaining dimensional stability. This gives every UAV more capacity for sensors, power, or range.

Fatigue and Corrosion Resistance

Under cyclic loading, fiber-reinforced composites fatigue more slowly than many metals and do not corrode—an advantage for platforms with high operating frequencies and for maritime or outdoor applications.

Functional Integration

Multiple functions can be integrated into a single component—load-bearing structure, aerodynamic surface, and mounting points—all within a single laminate. This reduces the number of parts, weight, and assembly effort.

Radiotransparency for Sensors

Fiber-optic laminates are electromagnetically transparent and are suitable for antenna covers and radomes without interfering with the payload’s radio communication.

Temperature Stability

With the right matrix system, components maintain their dimensional stability across the entire operating temperature range—from high-altitude cold to the heat of an engine environment.

Design According to Composite Rules

Composites follow different design rules than metals. Load paths, laminate structure, and fiber orientation are specifically tailored to the respective UAV structure.

Fiber-Reinforced Composite Components for Drones and UAVs

Lightweight construction meets durability: fiber composite technologies that make the difference in the drone and UAV industry-for optimal performance, maximum efficiency and sustainable solutions.

The Connova Group is the prime contractor for the manufacture of the primary structure of the Aero2 Cargo drone from Dufour Aerospace. The load-bearing structure includes the main assemblies “wings” and “fuselage,” as well as many other secondary components. The entire structure is manufactured using carbon-fiber-reinforced plastic (CFRP) construction—incorporating some highly innovative design principles that are being used for the first time worldwide in components of this kind. True to the motto: New Ways in Composites!

CFRP fuel tank

Integrating a fuel tank into an already tightly packed drone is typically a particular challenge. Not only is precise control of the center of gravity a key requirement, but so is the fundamental question of whether—and to what extent—the tank should bear structural loads. Weight optimization, leak-tightness, center-of-gravity control, and slosh protection are what turn a CFRP tank into a “flying” CFRP tank. We are proud to have already implemented various tank projects for aircraft—the external shape is no limitation for us.

CFRP rotor blade

Every propeller—whether for an aircraft engine or a helicopter—requires rotor blades tailored to its size and power. Precision and quality influence the aircraft’s performance characteristics and reliability. Commercial solutions are often unavailable for rotor blades that meet these requirements. Connova’s engineers therefore specified, developed, tested, and, in collaboration with the customer, qualified CFRP rotor blades for a drone weighing over 100 kg. The material and development data obtained represent a valuable asset for similar projects.

Dufour Aerospace – Aero2 Composite Airframe

The Connova Group is pleased to confirm its selection as the primary supplier for Dufour Aerospace’s Aero2 composite airframe. The fuselage’s key components—the main wing, fuselage, and engine nacelle—are manufactured at the Connova AG production facility in Villmergen (Aargau), Switzerland.

UAV Composites for Defense & ISR

Unmanned reconnaissance and surveillance platforms place special demands on lightweight construction, stiffness, and reproducibility. Connova manufactures lightweight, high-strength carbon-fiber-reinforced plastic (CFRP) structures for defense and ISR applications—from airframes to payload structures.

Applications & Platform Types

From fixed-wing aircraft to cargo drones: We develop and manufacture composite structures for the entire spectrum of unmanned platforms.

What advantages do carbon fiber composites (CFRP) offer for UAVs and drones?

CFRP offers a stiffness-to-strength-to-weight ratio that surpasses that of aluminum and titanium. For UAVs, every kilogram of structural weight saved directly increases payload, range, or flight duration. Added to this are fatigue and corrosion resistance, as well as the ability to integrate multiple functions into a single component.

Fuselages and airframes, wings and spars, rotor blades and propellers, conformal fuel tanks, payload and gimbal structures, RF-transparent antennas and radomes, landing gear, as well as fairings and flaps—from individual components to the complete primary structure.

Yes. Connova transforms prototypes into reproducible small- and medium-volume production runs—the typical batch size in the UAV market. The processes (prepreg autoclave, RTM, hot pressing) are selected based on the quantity, geometry, and load requirements.

Prepreg autoclave, RTM, hot pressing, winding, vacuum infusion, and wet lamination—all handled in-house and combined as needed for each project.

Compared to aluminum and titanium alloys, a 30–50% reduction in structural weight can be achieved, depending on the component.

Yes. Our quality management system is certified to EN 9100 for the aerospace industry, supplemented by ISO 9001. This means that unmanned aircraft are subject to the same quality standards as manned aircraft.

Yes. Both have been implemented as reference projects—including critical component inspections and leak testing for the tank, as well as the design and qualification of rotor blades for UAVs weighing over 100 kg.

Yes. We supply lightweight, rigid structures for reconnaissance and surveillance platforms. Learn more on the “Composites for Defense” page.

From feasibility studies and design to process development and prototyping, all the way to quality-assured series production—with a single point of contact throughout the entire lifecycle.

Yes. Fiber-optic laminates are electromagnetically transparent and protect the payload’s radio link without interfering with it.
