Modular aircraft
A modular aircraft or pod plane is a type of aircraft design where the payload carrying part can be detached from the rest of the aircraft. In this way, the aircraft can have a much-reduced loading and unloading time or change between different configurations of cargo or passenger capability.[1] Pod planes have two main components: the flying component: airframe, cockpit and engines; and the capsules: detachable pods (cabin or cargo hold). The flying component and the individual capsules can be detached from each other and combined in different ways.

History

In November 1950, the Fairchild XC-120 Packplane first flew. This was an experimental military transport for the U.S. Air Force. Described as a futuristic "pod plane", it was a development of the C-119 Flying Boxcar. Although tested, the project was canceled without any further production.[2]
In 2005, the Air Force Research Laboratory proposed a similar concept for military and civilian use in the configurable air transport: a blended wing body aircraft with multiple detachable, ground-mobile pods.[3]
The Clip-Air has been proposed since 2009 by the École Polytechnique Fédérale de Lausanne.[4] A 60 m wide flying wing includes the cockpit, engines and fuel, and can lift up to three 30 m long, 30 tons modules for freight, fuel or 150 passengers.[5]
Later, in 2017, Akka Technologies proposed a modular aircraft concept.[6]
Carpinteria, California-startup Dorsal Aircraft wants to make light standard ISO containers part of its unmanned freighter structure where the wing, engines and tail are attached to a dorsal spine fuselage. Interconnecting 5–50 ft (1.5–15.2 m) long aluminum containers carry the flight loads, aiming to lower overseas airfreight costs by 60%, and plan to convert a C-130H with the help of Wagner Aeronautical of San Diego, experienced in passenger-to-cargo conversions.[7]
