detachably attaching the propulsion module to the upper portion
of the fuselage means. Hall is therefore seen as disclosing the
subject matter of claim 13 except for the propulsion module being
adapted to carry forward and aft engine means.
With respect to independent claim 18, Hall discloses a
method of providing a fixed-wing aircraft with engine propulsion,
comprising the steps of forming a propulsion module A having a
housing adapted to be juxtaposed to a dry-wing aircraft fuselage
B, mounting an aircraft engine 50 having a tractor propeller 51
on the propulsion module, and including an engine fuel
compartment 56 within the housing of the propulsion module.
Hence, Hall discloses the subject matter of claim 18 except for
mounting on the propulsion module A an aft engine having a pusher
propeller aligned with the tractor propeller 51.
