Technical Details
Otto Aerospace has completed the preliminary design review (PDR) for Phantom 3500, a hyper-efficient business jet. The phase confirmed aerodynamic layout, system integration, and structural strength calculations. The project now moves to detailed design, manufacturing prep, and flight test planning.
A key innovation is the absence of traditional windows. Instead, panoramic digital screens display real-time camera feeds, enabling a smooth fuselage for improved airflow. Engineers use laminar flow technology to reduce drag by 35% and emissions by 90%.
Context and Background
Phantom 3500 builds on the Celera 500L prototype, which conducted over 50 test flights. The new jet is a full-scale turbofan business aircraft competing with Challenger 3500 and Praetor 500. It features Williams FJ44 engines compatible with sustainable aviation fuel (SAF) and a 6,850 km range.
Industry Impact
Phantom 3500 could cut fuel consumption by 50–60% using composite airframes and aerodynamic wings. The cabin height is nearly 2 meters with a flat floor. It can take off from 1 km runways. Flexjet signed a $5.85 billion contract for 300 units. Composite parts will be produced with Italian firm Leonardo S.p.A.
