Integrated Propeller Plane Concept Makes the Case For All-electric Airliners
Conseil et Technique is proposing to replace wing-mounted turbofans with an electric propulsion system installed around the rear fuselage of airliners.

Independent aerospace technology innovator Conseil et Technique hopes that 2021 will be the year it finds backers for its radical reboot of the traditional airliner powerplant configuration. The French company’s Integrated Propeller Plane (IP2) concept involves completely removing the standard turbofans from the wings and replacing them with a pair of counter-rotating, ducted fans driven by brushless electric motors and solenoid valves coiled around the rear of the fuselage just in front of low-profile V-shaped tail.

Observers looking at a concept loosely based on a standard narrowbody aircraft like the ubiquitous Airbus A320 family will immediately wonder how current battery-electric power could possibly drive an aircraft of that size, with standard payloads and routes. Conseil et Technique proposes to strip out as much as 30,000 kg (66,000 pounds) of weight, allowing it to carry enough batteries to fly an A320 for 78 minutes based on current average energy density assessed at 0.15 kWh/kg.
