Inventor and Patent Holder of the StratosLiner Aircraft Concept. Aggressive environmental demand can be raised sooner than we expect, and the mature cantilever concept can be found insufficient for further improvements. Something better, something future-proof is needed. StratosLiner is a platform with many options. The preferred slim-body embodiment is lifted in 4 points, forming a strong and stiff airframe with distributed load. Can be built of more composites. The 3rd wing has a folding outboard section (option). The depicted model is a very large, long-range transonic aircraft, for 600+ passengers, with hybrid turbo-electric propulsion.A comprehensive CFD study has been completed. The design is in a conceptual phase, but this study can display qualities and reveal teething issues. All issues seem to be possible to solve in a regular R&D process (that should follow). It is not only about aerodynamics; features, possible improvements and implementation of new technologies are discussed as well. Currently, I am awaiting responses from experts, new issues and their respective solutions to be considered when the detailed design will be developed. Ideas, comments and research proposals are welcome.
