FFA After graduation 1949, as Master of Science engineer in
aeronautics at
KTH Royal Institute of Technology, Stockholm Sweden he worked at the FFA, the Swedish
National Aeronautical Research Institute.
Saab From 1954 to 1967 at
Saab AB, he participated in the aerodynamic core of the projects for
Saab 35 Draken and
Saab 37 Viggen, both cutting-edge technology during the
Cold War and the
Nuclear arms race. He worked under
Erik Bratt and
Tore Gullstrand, in the Saab design team with
Hermann Behrbohm,
Olof Ljungström and
Einar Bergström. In the shadow of the
Cold War and the
nuclear arms race the client, the
Swedish Air Force's desire in the 1950s to the 1970s (the
Defence Act of 1958) was to be able to swiftly attack strategic
nuclear weapons-
bombers such as
Tupolev Tu-16 before they reached their targets. This with really fast
supersonic-
delta wing-
fighter aircraft such as
Saab 35 Draken, where
speed and
preparedness were the key factors. The
Swedish Air Force's need were also
landing operation-defenses over the surrounding seas with
attack aircraft as well as ultra-fast
reconnaissance aircraft planes such as the
Saab 37 Viggen. Economy and
materials engineering for
friction heat of the
atmosphere set the limit for speed. This generated large orders to build a very large air force and resources for
development. Dillner and
Hermann Behrbohm made significant efforts in the design of
Saab 37 Viggen, and in particular the design and tests of the
canard-wing construction.
Boeing From 1967 to 1981, Dillner was employed by
Boeing Commercial Airplanes in
Seattle, US to work with the supersonic
Boeing 2707 SST passenger jet 1967–1972. At Boeing he also become involved with the aerodynamics of the extreme supersonic aviation at the re-entry of
Space Shuttle 1971-1972 and Boeing Preliminary Design Group and ex
QSRA transporter studies. Dillner was aerodynamic chief engineer at Boeing Commercial Airplanes 1972–1981. He also became an American citizen while in Seattle. From 1981 to 1988, Dillner was employed by
Boeing Defense, Space & Security in Seattle as aerodynamic chief engineer 1981-1985 and chief engineer 1985-1988 until his retirement. After retirement, he made some consulting assignments were made for
Aermacchi and
Saab 2000. ==Compound life==
