Overview

The UAV That Started the Talisman Legacy
First Flight: 2015

The TS-25 was Elytron Aeronautica's first operational unmanned aircraft and the technological foundation upon which the Talisman family was later developed.
Designed as a conventional take-off and landing (CTOL) aircraft, the TS-25 combined long endurance, autonomous operation and exceptional payload capability within a compact and efficient airframe.

More than a prototype, the TS-25 became a foundational technology and development platform for autonomous flight technologies, payload integration and mission validation, laying the foundations of Elytron's UAV expertise and future development programs.

Designed as an aircraft

The TS-25 was conceived as a true aircraft from the very beginning.
Its development focused on delivering the efficiency, reliability and endurance of conventional aviation while integrating the advantages of modern autonomous flight systems.

The aircraft was engineered around:

Conventional Take-Off and Landing (CTOL)

Autonomous Navigation

Tandem-Wing Aerodynamic Architecture

Modular Payload Integration

Long-Endurance Operations

Rapid Field Deployment

This approach resulted in a UAV capable of performing demanding missions while maintaining operational simplicity and low operating costs.

Tandem-Wing Configuration

The TS-25 employed Elytron's proprietary tandem-wing configuration.
Unlike conventional layouts, the tandem-wing architecture utilizes two lifting surfaces working together to generate lift, stability and control.

Key advantages include:

High Lift Efficiency

Enhanced Stall Resistance

Reduced Wing Loading

Increased Internal Volume

Excellent Low-Speed Handling

Compact Overall Dimensions

The aircraft incorporated proprietary laminar airfoils specifically developed for the configuration, contributing to the system's efficiency, stability and endurance.

The same engineering philosophy would later evolve into the larger Talisman family, preserving the core aerodynamic principles validated on the TS-25.

Flight-Tested and Validated

The TS-25 accumulated extensive flight experience through numerous flight campaigns conducted from its maiden flight in 2015 onwards.
The aircraft was used to validate:

Aircraft Performance

Mission Planning

Autonomous Flight Functions

Flight Control Algorithms

Payload Integration

Operational Procedures

Navigation Systems

The knowledge gained through these activities directly contributed to the engineering methodologies later applied across the Talisman product family.

UAV Navigation Case History

The maturity of the TS-25 attracted the attention of UAV Navigation during the development of Elytron's autonomous flight capabilities.
In 2018, the aircraft was selected for a dedicated VECTOR Flight Control System integration and adaptation campaign performed onsite at Elytron Aeronautica's facilities in Italy.

Despite its non-conventional tandem-wing architecture, the aircraft demonstrated excellent flight qualities throughout the adaptation process.

The complete integration, configuration and tuning campaign was successfully completed in less than two weeks.
Following the campaign, the aircraft became fully capable of:

Autonomous Take-Off

Autonomous Landing

Autonomous Navigation

Fully Automated Mission Execution

According to UAV Navigation's published case history, the aircraft demonstrated excellent flight behaviour and quickly achieved stable autonomous operation despite its unconventional aerodynamic layout.

The successful collaboration established the foundation for a long-term technical relationship and validated the TS-25 as a professional autonomous UAV system.

This collaboration provided independent validation of the aircraft's flight performance, controllability and autonomous capability, further confirming the maturity of Elytron's tandem-wing architecture.

HIGH PAYLOAD CAPABILITY

One of the defining characteristics of the TS-25 was its exceptional payload-to-size ratio.

The aircraft was designed around a large and easily accessible payload compartment capable of accommodating:

EO/IR Sensors

Mission Computers

Mapping Systems

Communication Systems

Telemetry Equipment

Additional Fuel Capacity

More than 40% of the available fuselage volume was dedicated to fuel and mission equipment, enabling rapid reconfiguration for different operational requirements.

The spacious payload bay allowed the integration of mission-specific equipment while maintaining aircraft balance and endurance.

This payload flexibility laid the foundation for the modular mission architectures later adopted across Elytron's UAV platforms.

Engineered for Operational Flexibility

The TS-25 was designed around practical field operations.

The aircraft structure consisted of only three primary assemblies:

Fuselage

Front Wing

Rear Wing

This modular architecture enabled rapid transportation, assembly and maintenance.

The landing gear was specifically designed to support operations from semi-prepared and unprepared surfaces, increasing operational flexibility while reducing infrastructure requirements.

Applications

The TS-25 was more than a technology demonstrator.
It was a versatile operational aircraft used to validate mission concepts and payload integration strategies that would later influence Elytron's future UAV developments.
