Glorieuse on Zlin Norden 915iS

New “Glorieuse E-PROPS” constant speed propeller, tested on Savage Norden by Zlin Aviation. Here is the first feedback.

“The barrier of real 125 mph (201 km / h) cruising speed with 26” bushwheels tires and 1.367 lbs take off weight (620 kg) has finally been broken.

We already knew it was possible with our E-PROP 4-blade ground adjustable propeller ( with an adjustment that would allow these speeds but going to lose in take-off and climb performances), but now with the brand new and more efficient 3 blade E-PROP Glorieuse “constant speed propeller”, these performances become a solid reality for our customers…

Testing it in collaboration with our Czech dealer Mr. Marek Hyka, we can share some interesting preliminary datas since the combinations between engine rpm, map, consumption etc, are truly multiple and will require some time.

Here some of the interesting results (20° celsius outside temperature/1.000 ft ASL/ 1.025 mbar):

• Economic cruise speed at 4.650 rpm with 29 MAP and 4.6 USGal/h – 17.5 lt/h consumption: 101 mph IAS (163 km/h) – 103 mph TAS (166 km/h)

• Normal cruise speed at 4.880 rpm with 35.8 MAP and 6.3 USGal/h – 23.8 lt/h fuel consumption: 119 mph IAS (191 km/h) – 121 mph TAS (195 km/h)

• Fast cruise speed at 5.200 rpm with 44 MAP and 8.9 USGal/h – 34 lt/h fuel consumption: 132 mph IAS (213 km/ h) – 135 mph TAS (217 km/h)

Interesting to mention that we experienced these results with a flying weight above the allowed MTOW and with 26″ bushwheel tires, not with the standard 22″ ones.

We have not yet tested the max power/max speed in level flight.

By the end of the month we will have all the data report and we will finally release our new website !”
