Validation flight of the 3-blade ASCALON on our Jodel DR1054

On June 25th, 2026, our pilot Samy carried out a validation flight with the 3-blade ASCALON Carbon propeller installed on our Jodel DR1054, powered by a Lycoming O-320 150 hp engine.

This flight is part of the ongoing validation of the ASCALON propeller range, developed by E-PROPS for direct-drive Lycoming and Continental engines. The ASCALON range includes 2-blade and 3-blade propellers with ground-adjustable pitch, full Carbon construction, and Titanium leading edge protection.

The goal of this flight was not to conduct a formal test campaign, but to continue real-flight validation of the propeller in normal operating conditions. This kind of flight helps confirm the behavior of the propeller on the aircraft, its smooth operation, installation suitability, and overall consistency in day-to-day use. It also allowed us to verify in flight that the 3-blade ASCALON is a very quiet propeller, as expected from its design.

All these validation flights are carried out at Sisteron-Vaumeilh airfield (LFNS), in Provence, where the E-PROPS factory is located. This is a major advantage for our development work: our design office, our workshop and our 3 aircraft are all on the same airfield.

ASCALON propellers are designed to be lightweight, strong, and efficient. The 3-blade version weighs about 7 kg. The range has been developed to minimize vibration and noise while delivering high performance on direct-drive engines.

Our nice Jodel DR1054 is a very relevant platform for this work. With its Lycoming O-320 150 hp engine, it allows us to validate the ASCALON 3-blade propeller on a well-known and practical aircraft configuration. E-PROPS also reports measured performance gains on the Jodel DR1054 with ASCALON, including improvements in takeoff, climb, cruise efficiency, and noise reduction compared with other propellers in real operating conditions.
