H55 High-Density Altitude Electric Flight Demonstration
Sector: Airport • Location: Centennial, Colorado, United States
Source: Design and Development Today
H55 completed a series of high-density altitude, high-temperature demonstration flights in Colorado using the H55-powered Bristell B23 Energic aircraft. The flights tested aircraft performance in extreme conditions, specifically at an airfield at 5,800 feet above sea level with temperatures reaching 36°C and a takeoff density altitude of 9,500 feet. The electric propulsion system demonstrated cons

Description
Description | H55 completed a series of high-density altitude, high-temperature demonstration flights in Colorado using the H55-powered Bristell B23 Energic aircraft. The flights tested aircraft performance in extreme conditions, specifically at an airfield at 5,800 feet above sea level with temperatures reaching 36°C and a takeoff density altitude of 9,500 feet. The electric propulsion system demonstrated consistent climb rates and efficient battery cooling, proving operational performance in challenging environments. |
