Hi-Flow Fuel System


by BVM

 

BVM is always interested in the future of jet model airplanes and how to make our current products even better.

The fuel supply system for larger turbine powered models is our  latest area of this "improved" interest.  While our current system has been working well for several years, it has been noticed that it can be sensitive to installation error and certain engine fuel pump irregularities.

Thus the all new BVM Hi-Flow Fuel System

Every component, from the Brass Clunks in the tanks to the fittings on the U.A.T. have been made larger. This includes: elbows, tubing, "T's", over flow fittings; as we stated, "Everything"!

Results

A side-by-side bench test of our standard system against the new Hi-Flow system, demonstrated 1/3rd of the fuel flow resistance.

Note: Subject model was a BVM Ultra Bandit with the 6.2 liter fuel tanks and a JetCat P-200.

Note: System demand was measured by applying a vacuum gage to the fill fitting on the U.A.T.

Benefits

With this whopping extra margin of "eased" fuel flow, the system can now even tolerate bits of junk like filings, or dirt in the fuel tanks, without impeding engine operation. The engine fuel pump power demands are reduced, adding service life to this critical item. There will be no combination of throttle movement vs. aerobatic maneuver that can exceed the Hi-Flow system's supply capability.

What Engines Need The Hi-Flow System?

Certainly, turbine engines in the 180 class (40+ Lbs) of thrust or larger will benefit from the Hi-Flow system.

Flight Tested

Like all BVM Jets products, the Hi-Flow Fuel System has been thoroughly flight tested.

 

Hi-Flow Testimonial  08/01/2014

David Soufer called to tell us how much he likes his Ultra Bandit "Hi-Flow Conversion".

 David is using a JetCat P300 engine (turned down and with the speed limiter set to 200 mph) and reports measurable lower voltage demand on the fuel pump.  David logged 4 flights on the system on his first outing and confirms that what BVM says about the "Hi-Flow Conversion" is absolutely true. He says that even the fueling and defueling process proceeds very quickly without any strain on the system.  David enjoys a new confidence in this totally bubble free BVM "Hi-Flow" system.
