JetCat-PRO Engines Functions - Integrated Engine-Sided Components:
- ECU (Electronic Control Unit): Fully programmable via a detachable Ground Support Unit (GSU), allowing for easy configuration and adjustments.
- Brushless Starter & Seal-Free Brushless Fuel Pump: High power, efficient brushless systems reduce wear and improve reliability.
- Fuel & Kerosene-Start Solenoids: Integrated into the turbine for smoother and more efficient startup.
- Post Fuel Filter: Located downstream of the pump, this last-barrier filter ensures clean fuel delivery.
- Barometric Altitude/Pressure Sensor: Automatically tunes the engine to its operating altitude, optimizing performance at various heights.
- 4-Pin Molex Expansion Connector: Allows for the connection of additional accessories like smoke pumps, fuel transfer pumps, or the GSU.
- Optional Bleed-Air Port: Can be used for pressurizing the fuel system, enhancing engine reliability at high altitudes.
Key Engine Functions:
- Kerosene Quick Start System: Uses a high-speed, low-current ignition system for direct startup on kerosene, eliminating the need for preheating or glow plugs.
- In-Air Restart Capability: Optimized for high-altitude and high-speed in-air restarts, ensuring continuous operation even in demanding flight conditions.
- Automatic Engine Cool Down Cycle: After engine shutdown, the turbine automatically enters a cool-down cycle to protect the internal components.
- Fuel Monitoring & Reporting: Provides real-time data on fuel consumed, fuel flow rate, fuel burned, and the remaining fuel in the tank, enhancing operational awareness.
Advanced Control and Safety Features:
- Voltage-Controlled Power Management: The engine/ECU can be turned on or off via a voltage control signal, removing the need for external power switches.
- Engine Safety Shutdown Input: A flight termination system ensures the engine can be instantly shut down. This system kills the power to the fuel pump, closes the solenoid valves, and stops the engine through multiple redundant safeguards, while allowing the ECU to remain powered for continued data reporting and engine cooldown.
- Comprehensive Monitoring: All currents and voltages (e.g., supply voltage, pump driving voltage) are continuously monitored, along with vital engine life parameters and setpoints, to provide a detailed operational overview.
Additional Features:
- Automatic Fuel Purge Feature: The system automatically fills and purges the fuel feed lines, stopping the purge once fuel reaches the engine, simplifying the startup process.
- High-Performance Ceramic Bearings: Ensures long-term durability and smoother turbine operation, even under extreme conditions.
This combination of cutting-edge technology and safety features makes the JetCat P250-PRO-S-V2 a top choice for those seeking high performance, reliability, and advanced functionality in their turbine engines.
