The RLM (Reichsluftfahrt-Ministerium) issued
a specification for a single-seat shipping attack aircraft on February
18, 1943, to combat the anticipated invasion of Europe. Although the specification
called for a piston-engined powered aircraft, but it was soon realized
that only a turbojet could hope to match the proposed performance requirements.
Henschel submitted a design for RLM approval in April/May 1944 (wind tunnel
testing had already started, see wind tunnel model below), which was approved
as the Hs 132. The fuselage was of a circular cross-section, and
constructed entirely of metal, and the single BMW 003 jet engine was mounted
on the fuselage top. The mid-fuselage mounted wings were mostly of wooden
construction, and had a slight taper on the leading and trailing edges.
Due to the position of the engine, a twin fin and rudder configuration
was chosen, to allow the jet to exhaust without interfering with the tail
unit. A tricycle landing gear was to be used, with the nose wheel revolving
90 degrees to lie under the cockpit when retracted; the main gear retracted
inwards. The extensively glazed cockpit was completely faired in with the
rest of the fuselage, and the pilot was in a prone position, the better
to withstand the intense G-forces of the fast, steep dive during the bomb
run. The pilot's controls featured a spring-operated power rudder, since
a pilot in the prone position could exert less pressure on the rudder controls.
The flight
profile had the Hs 132 begin its high-speed attack at a range outside the
ships' range of fire. After reaching a speed of 910 km/h (565 mph) in a
shallow dive, the pilot would then climb as he released his bomb. The bomb
would be "tossed" at the target using a type of primitive computerized
sight, which delayed construction of the aircraft because it was not ready
in time. The prone-pilot position was extensively tested on the Berlin
B-9, a twin engined test aircraft built to test G-forces.
A contract for
six prototypes was approved in May 1944, and construction was begun in
March 1945. There were four versions of the Hs 132 proposed (see table
below), including the Hs 132D, which was to have an enlarged (9.1 m (29'
10")) wing. The Hs 132V1 was nearly complete, with the fuselage completed
at Henschel's Berlin-Schönefeld facility and the wings being finished
at Henschel's French subsidiary. Although the Hs 132A was scheduled to
have its first flight in June 1945, the wings and fuselage were never mated,
and Russian forces captured the intact fuselage in May 1945.
