ABSTRACT:
A ducted propeller aircraft from which visibility is excellent and which is capable of operating quietly and efficiently has a propeller shroud which serves as a primary load path to pass bending and torsional stresses to which the mainplane is subject in use between the portions of the mainplane either side of the shroud, the shroud defining a duct which is unimpinged upon by any portion of the turbulent airflow emanating from the mainplane.
