Tango VTOL UAV

Technical specifications

Design

Payload Bay

The payload BAY is generously sized, offering abundant space, and is designed to safeguard precious cargo. It boasts a capacity unmatched in its class, allowing for the inclusion of more beneficial payloads or supplementary drive elements.

It can house a hydrogen tank for an optional fuel cell system. The payload module is available in a sealed version, with an option for a mechanism to open and close the payload compartment. We also provide the optional installation of larger wings, significantly enhancing the aircraft’s load capacity and extending its flight duration.

Navy Version

The Tango™ VTOL drone’s maritime model features IP55-rated rotors for water resistance and emergency sea landings. It allows easy cleaning, making it ideal for water operations and CBRN missions.

An automated system ensures secure ship landings. Its spacious payload bay supports various cargo, with optional larger wings boosting capacity and flight time. Propulsion options include:

• Electric

• Internal combustion

• Hydrogen battery

Cargo Version

In the CARGO version, we have designed a specialized flap located on the lower part of the fuselage, which can be operated either manually or via the autopilot system.

This feature enables precise air-drop or delivery of the packages or goods being transported. The release of packages or materials can be executed:

• With a parachute

• Without a parachute
  depending on the specific requirements.

Modular Design

The drone features a versatile modular design, allowing for in-field payload adjustments without altering its configuration.

Typical workflow:

• Orthophoto mission

• Followed by multispectral survey

The drone fits into a personal vehicle when housed in its case. Assembly is straightforward; while two people are recommended, it can be easily assembled by a single person.

Electronics

Full UAVCAN Integration

UAVCAN is a protocol providing a highly reliable communication application via the CAN bus, making communication within drones more resistant to interferences.

Benefits include:

• Faster access to system data for ground crew

• Real-time feedback on servos, pitot tubes, rotors, etc.

• Improved operator response to potential operational errors

Redundant Power Supply

A new Carrier Board, designed and manufactured by ElevonX, integrates the autopilot and all electronics on a single secure circuit board.
The power supply unit is double redundant in case of emergency.

Cable Harnesses

High-quality harnesses are made in-house and customized to meet any specification. The wiring is secured against:

• Vibrations

• Abrasions

• Moisture

Navigation Lights

Designed for the drone to be visually detectable despite various weather conditions.
These lights can be deactivated if the mission necessitates stealth operations.

Composites

Structurally Optimized Hull

The hull is made in one piece, resulting in a structurally stronger monocoque body.
Two-piece hulls introduce joints that are mechanically and chemically weaker and more prone to failure.

Prepreg Composite Technology

Prepreg material is a composite of fabric and uncured resin, pre-impregnated to form a laminate with a precise fabric-to-resin ratio.

This ensures:

• Consistent Ultimate Tensile Strength (UTS)

• Stable Modulus characteristics

• Reduced variability compared to traditional hand layups

Composite Optimization

Pre-impregnated fabrics provide:

• Optimal material properties

• Superior consistency and quality

• Guaranteed repeatability of weight and performance

Manufacturers supply cured ply density data, enabling accurate weight prediction before cutting. In contrast, wet layup and infusion methods introduce uncertainty until final production.
