Lowering Operational Costs,Increasing Cruise Speed and Profitability While Adding Flexibility

For Cessna Caravan 208BEPIC CARAVAN

The Cessna Caravan has long been recognized as a dependable, utilitarian,

single-engine turboprop aircraft with a robust design and workhorse attitude.

In keeping with Raisbeck’s mission to improve the productivity and efficiency

of business aircraft, Raisbeck’s team of engineers saw a clear opportunity with

the Cessna Caravan 208B equipped with a factory cargo pod to reduce drag

which adversely impacts the aircraft’s cruise speed, fuel consumption and

engine ITT. Reducing drag would significantly improve the Caravan’s overall

efficiency and increase profitability for its operators.

EPIC Caravan is the end product of that vision: a drag reduction system

engineered to be as tough as the Cessna Caravan 208B that gives operators the

choice of faster cruise speeds or reduced fuel flows and ITT, making operations

more cost-effective, flexible and profitable. As a bonus, lower fuel flows result

in lower emissions, making operations more environmentally friendly.

COMPONENTS OF THE EPIC CARAVAN

Expanding Your Operational Profitability

DUAL AFT BODY STRAKES• Decreased drag results in increased climb and cruise

performance

• Pilot control and handling qualities are enhanced

• Equivalent vertical tail area is increased, smoothing the airflow from the cargo pod and forward fuselage, thereby improving directional stability and ride comfort

FORWARD CARGO POD FAIRING• Reduced drag results in increased climb and cruise

performance

• With Raisbeck’s design, the need for a cargo pod de-icing boot is eliminated, resulting in lower maintenance costs and less downtime with no impact on the aircraft’s FIKI authorization

• The forward fairing’s streamlined design eliminates the trapping of airflow behind the nose gear and in front of the leading edge of the cargo pod

EPIC CARAVAN CFD VISUALIZATIONSidentify opportunities to improve efficiency

Baseline highlights high drag regions at front of cargo pod

Raisbeck fairing reduces drag and smooths airflow at front of cargo pod

Baseline highlights regions of high drag and turbulent airflow under aft fuselage,

creating drag and inducing yaw

Raisbeck strakes reduce drag and smooth airflow under aft fuselage, eliminating yaw and improving control/handling

INCREASED CRUISE SPEEDAt fixed power setting/fuel flow, EPIC Caravan adds 4-5 ktas of airspeed

FUEL SAVINGSAt fixed airspeed of 175 ktas, EPIC Caravan reduces fuel flow by ~2.6 gal/hr

REDUCED ITTAt a typical175 ktas fixed airspeed, EPIC Caravan results in ~15ºC reduction in ITT due to reduction in drag and associated power required for level flight
