New version H16BL2

posted in: Public Info | 0

We are happy to introduce you our new upgraded version of our engine – H16BL2. Key difference between H16BL and H16 is the new machined compressor wheel, designed in house. For our customers this means 1kg more thrust and increased life of the impeller wheel which is made by 5 axis milling from high strenght aluminium alloy. And the best thing is that we were able to keep the price at the same level as for the H16BL engine! Hope you will enjoy the new 18kg thrust.

NEW – Fuel Shut Off Valve

posted in: Public Info | 0

We are introducing new product form Hybl Turbines: the Fuel Shut Off Valve.

It is a servo operated safety valve to be installed between fuel tank and engine pump. Operated by independent RC channel, you can safely cut off the fuel flow in case fire, fuel leak or turbine is out of control. The valve can be also used anywhere you need a high throughput servo controlled valve. It uses standard 6mm push in fittings. The ball valve has 5mm bore for high flow capacity. Weight 84 grams.

Price: 75 EUR incl 21% VAT

We prepared for you a simple to use Engine Deck. Using this program you can calculate engine trhust under different ambient condition. It may also be used for engines of different brands. Go to Downloads section to get the program.

High “EGT” explanation

posted in: Public Info | 0

We have been asked couple times why the H16 engine has so high Exhaust Gas Temperature (EGT).

The explanation is very simple and was also described in the H16 engine review in RC Jet International April/May 2015 issue.

The H16 engine unlike others has temperature probe positioned infront of the turbine, thus measures approx 150°C (at full power) higher temperature than if placed behind the turbine due to temperature drop in the turbine stage. Typicaly the H16 max EGT is around 680°C and is precisely measured during each engine release test using 4 circumferentialy displaced external probes. Based on this measurement the engine temperature limit is calculated and set in the Engine Control Unit.

To wrap it up, there are no user drawbacks of this approach and it is fully equal to EGT measurement.

Long run test – 60hours and 780 starts logged

posted in: Public Info | 0

Big milestone has been achieved. Our H16 engine dedicated for accelerated cycling test has logged 60 hours and allmost 800 starts in our ground test cell. (allmost 1000 litres of JetA1 🙂 )

Engine is tortured by computer controlled short time intensive test runs to prove low cycle fatigue life and also by stair step tests to prove high cycle fatigue life.

The engine is still in perfect condition and we continue… 🙂

We are preparing now a diesel fuel test on the same engine.
