Cessna 208B Grand Caravan — Systems Description

This document provides a comprehensive overview of the hydrogen-electric propulsion system designed for the Cessna 208B Grand Caravan. It discusses the technical aspects of the ZeroAvia ZA600 powertrain, which aims to retrofit existing Caravan aircraft for zero-emission flight. The document outlines the operational benefits, environmental impact, and economic advantages of transitioning to hydrogen-electric technology. It is intended for operators, maintenance personnel, and stakeholders interested in sustainable aviation solutions. Key topics include aircraft performance, retrofit procedures, and the future of hydrogen infrastructure at airports.

• The ZA600 powertrain delivers 500 to 750 kW of continuous power for the Cessna 208B Grand Caravan.
• The hydrogen-electric Caravan can achieve a range of 250 nautical miles with a payload of 9 passengers or 855 kg.
• Operators can expect operating cost savings of 30-50% compared to traditional fuel systems.
• The retrofit process involves removing the existing turbine engine and installing the hydrogen-electric powertrain.
• ZeroAvia is developing airport refueling infrastructure to support hydrogen-electric operations.
