TULPAR Drone Flex

TULPAR Drone Flex is a next-generation, self-sealing flexible fuel tank system engineered specifically for unmanned aerial vehicles (UAVs) operating in high-risk, contested, and remote environments.

Unlike conventional rigid fuel tanks, Drone Flex is designed as an integrated airborne fuel system, prioritizing survivability, weight efficiency, and platform adaptability. Its flexible architecture allows seamless integration into UAV fuselages or modular fuel pods while maintaining structural integrity under vibration, altitude changes, and thermal cycling.

When equipped with optional BUYAN self-sealing coating, TULPAR Drone Flex provides enhanced ballistic resilience, enabling continued mission capability even after projectile impact.

Features

  • UAV-Specific Flexible Fuel System
    Designed for aerial platforms where weight reduction and adaptability are mission-critical.
  • Advanced Internal Fuel Bladder
    Polymer-coated, double-sided membrane reinforced with nylon fabric for aviation fuel compatibility and long-term durability.
  • ASTM-Validated Materials & Seams
    Material strength and weld integrity tested in accordance with relevant ASTM standards for aerospace and defense applications.
  • High-Frequency (HF) Welded Seams
    Provides uniform seam strength, superior leak resistance, and durability under cyclic loading and UAV vibration profiles.
  • Optional BUYAN Self-Sealing Ballistic Protection
    Self-healing coating seals penetrations caused by ballistic impact.
    Ballistic testing demonstrated no fuel leakage after 7.62×51 mm AP ammunition impact.
  • Modular & Fully Customizable Design
    Available in multiple volumes with configurable inlet/outlet ports and flanged interfaces.
  • Anti-Slosh Fuel Stability (Optional)
    Polyester anti-sloshing foam improves fuel stability, center-of-gravity control, and flight performance.
