Presumably you've discovered Raymer, Stinton and Roskam? Also FAR-25 and FAR-E, and you understand where they fit in relation to ICAO and the Chicago Convention?
And you're aware that the project you're describing at Cranfield (arguably the best aeronautical university in Europe) would be a project for probably a team of 20 students over one year?
You've also looked up Cranfield's past projects, and also looked at the outputs of the Cambridge/MIT "Silent Aircraft Initiative"?
Oh yes, and that aircraft is one word?
One imagines you are only doing conceptual design? Anything bigger would be impossible in a year.
