The document describes the Prandtl-D aircraft, which has a 24-meter wingspan. It is a tailless utility transport designed for simplicity and robustness, with single pilot operation and the ability to carry freight. The large wing area allows for short takeoff and landing distances without need for powerful lift systems. It has a carbon fiber shell and structure to reduce weight and maintenance needs. The design aims to make aircraft production globally licensed similar to popular vehicles.

Takeoff distance 300 meters Prandtl-D aircraJ 24.-meter wingspan
is a modern uElity transport aircraC and is designed to be the airborne equivalent of the
ubiquitous white vans seen on roads around the world. The design spec is therefore
simplicity and robustness. Single pilot operaEon with provision for pilotless ops when
regulaEons allow (freight only). Simple to fly, simple to maintain, simple to build and simple
to operate
Ø The tailless configuraEon was chosen to deliver on the simplicity. The large wing area
ensures low take-off and landing distances without the need for large and powerful high
liC systems. It also frees up the aC fuselage for a large clamshell door, the lower part of
which forms a loading ramp, while the upper part hinges completely out of the way for
loading of large cargo items. The nose secEon also hinges for end-to-end loading.
Ø The cross secEon of the fuselage is the same as an ISO container, so standard palleEsed
cargo can be efficiently loaded. The structure of the fuselage is a carbon fibre shell for
strength, light weight and corrosion resistance, allowing for carefree cargo handling. The
load bearing structure will be a carbon fibre sandwich, which will be made in a single large
mould and will reduce parts count by 90% compared with similar sized aircraC, which will
aid in reducing maintenance and inspecEon to almost zero as well as reducing
manufacturing/assembly Eme in producEon.
Ø The simplicity of the design will allow aircraC producEon to be licenced to manufacturers
all around the world and it promises to be the airborne version of the Toyota pickup or
minibus.
