The T191 Emergency Recovery Parachute System

1. Core Design & Operation

• Rocket Deployment System: A mechanically activated rocket ensures fast, forceful parachute ejection, critical for low-altitude emergencies where every second counts.
• Manual Activation: Pilots retain direct control to trigger deployment, ensuring responsiveness to unforeseen failures (e.g., engine shutdown, structural compromise).
• eVTOL Optimization: Tailored to vertical takeoff/landing dynamics, where low-altitude stalls or malfunctions demand immediate recovery—its rapid deployment (3–4s) and controlled descent mitigate crash risks.

2. Key Features & Advantages

• Rapid Response: Fast inflation and deployment times (3–4s under hovering conditions) minimize altitude loss in emergencies.
• Gentle Descent: Low stable descent rates (≤7–7.5 m/s) reduce impact to levels equivalent to a 2.5–2.9m fall, protecting occupants and equipment.
• Compact & Lightweight: Small form factors (e.g., 30x25x15cm soft pack for T191-350) and manageable total weights (9.8–15kg) avoid compromising platform performance.
• Robust Reliability: High inflation success rates, low opening overload (≤6g), and strong stability ensure consistent performance in critical scenarios.
• Extreme Durability: Operates in -40°C to +60°C, with a 12-year service life and 6-year maintenance intervals, ensuring long-term readiness.
