Hi,
Found this, as always by chance, while looking for something else. If it ever shows up beyond the patent stage, this would then be considered square one. I like this design, actually.
Patent No. CN102826216 (A)
Date Issued: 2012-12-19
Aerodynamic configuration of aircraft
Inventor(s): FU SONGHAI; LU SEN; LI PENGFEI; HU RUI; XIN RONGTI; LENG ZHIHUI; SHEN LIANG
Applicant(s): JIANGXI HONGDU AVIAT IND GROUP
Application number: CN20121333863 20120911
Priority number(s): CN20121333863 20120911
Abstract: The invention relates to the technical field of aerodynamic configuration design of aircrafts, in particular to an aerodynamic configuration of an aircraft. The aerodynamic configuration of the aircraft comprises an aircraft body (3), outer wing sections (1) and inner wing sections, and is characterized in that the surfaces of the outer wing sections (1) and the inner wing sections (2) are laminar flow airfoils; the inner wing sections (2) are wing-body transition sections, adopt back-swept wings with a moderate sweep back angle and a small span-chord ratio and are connected with the aircraft body; the wings and the aircraft body are fused together; and the outer wing sections (1) adopt forward-swept wings with a moderate sweep forward angle and a moderate span-chord ratio. Due to the aerodynamic configuration of the aircraft, not only can the requirement on high-altitude long-endurance high-subsonic-speed cruise of the aircraft be satisfied, but also the flight speed is improved and the problem of trimming difficulty is solved.
