Challenge NAE Le bourget 2017 Ensta premier démonstrateur volant du mini-bee VTOL hybrid

Technical Summary: ENSTAÉRO Report dated December 22, 2017

Overview: The 1/10th scale demonstrator has experienced delays against the initial schedule due to exam periods. Technical adjustments have been identified for stabilization, primarily focusing on mass reduction by 25%. Target mass achieved by modifying wing structure and battery type.

Wing/Structure Department: Polystyrene extruded material procured and wing fabrication completed at IUT Brest. Weight-saving carbon tubes integrated into wings. Technical adjustment made in mid-wing tube fixation by replacing plastic T-connectors with lightweight carbon T-connectors.

Electronics Department: Two quadcopter control boards selected for motor control. Raspberry Pi employed for tilt rotor management. Initial tests with control boards and mini drone proved successful. Procurement list and wiring plan established.

Landing Gear Department: Design plans for fiber-glass landing gear developed. Shock-absorbing spheres introduced for potential hard landings. 3D models of landing gears developed on Catia for future printing.

Schedule Update: Mechanical assembly and flight tests targeted for completion by mid-January.

Key Highlights:

Mass reduction of 25% targeted. Dual control boards for motor stability. Landing gear designed for durability and shock absorption. Timeline revised with a focus on January for mechanical completion and flight tests. This summary emphasizes key aspects concerning project status, technical challenges, and upcoming milestones.
