By increasing the efficiency of engine airflow, the Raisebeck Ram Air Recovery System (RARS) increases your King Air 200’s engine performance in normal and anti-ice conditions. The system effectively decreases ITT by 18° at equal torque, reducing fuel flow and increasing range, while preventing FOD and enhancing your aircraft’s all-weather capabilities.

UPGRADE BENEFITS

• Significantly improved climb and cruise performance with ice vanes stowed or deployed
• 18° cooler engine ITT at equal torque
• 8% increase in available horsepower
• 8% to 11% block fuel savings (as part of a Raisbeck EPIC package)
• Ice vanes may be deployed at any time including taxi and takeoff when OAT is ISA +27°C (as part of a Raisbeck EPIC package)  

ITT Reduction

• Utilizes Coanda-effect aerodynamics for efficient airflow vectoring
• Full inlet plenum sealing through unique full-body diaphragms

Further Enhancements

RARS maximum performance gains are obtained when paired with Raisbeck/Hartzell Swept Blade Turbofan Propellers as their twist extends all the way to the spinner, driving high-pressure air into the engine inlet.

Reduce Torque Loss with Ice Vanes Deployed

The patented Raisbeck Ram Air Recovery System maximizes airflow to the engine inlet, allowing the engine to retain the same power regardless of ice vane deployment. With the RARS, you experience consistent speed and power as you climb through clouds or inclement weather with ice vanes deployed. With the ice vanes stowed, you experience increased power and speed while saving fuel – all at lower engine temperatures.

Protect Against Foreign Object Damage (FOD)

With the Raisbeck/Hartzell Swept Blade Turbofan Propellers, or any EPIC[SS1] [CA2]  package prop, ice vanes may be deployed at any time – including on the ground, during takeoff, and for landing – when OAT is up to ISA +27ׄ°C. Use of ice vanes on RARS-equipped aircraft on the ground and during takeoff and landing minimizes the risk of foreign object damage. For this reason, the U.S. Army has equipped its entire C-12 fleet with the Raisbeck Ram Air Recovery System.
