ccording to the Convair Division of General Dynamics ^ the aircraft of
the future will weigh approximately 20% less than present-day aircraft and it
will be possible to build it and operate it more cheaply. This is because of
the increased use of plastic components.] Just like Goodmanson, Ken Carline,
director of the General Dynamics Programs for Advanced Transport Technology at
the Fort Worth facility, believes that high subsonic velocities can be reached,
1060 km/h at an altitude of 12,200 meters, by using supercritical wing profiles
and fuselage shapes designed according to the area rule. He also believes that,|
for the same amount of fuel as for conventional jets, lit will be possible to
transport larger payloads over larger distances, and that the flight character-
istics in the transonic velocity range can be considerably improved. It is
possible that the air frame, wing surfaces and possibly also fuselage components
or the entire fuselage of a transport aircraft designed by General Dynamics |
will be made of graphite fiber reinforced plastic, which is lighter than the
light metal alloys used today. As Carline states, "Large aircraft components
can be made in presses by using bonding materials". A weight reduction of 20%
and considerable cost savings are possible by avoiding the conventional cell
covering technologies. The surface quality of transport aircraft of the future
which General Dynamics is studying will also be considerably better than in the
case of present day jets, because there will be no rivets and less joints.
Carline states that wings made up of composite materials and advanced flight
control installations should make aircraft travel during the 80 's much more
comfortable for the passenger than is the case today. Transducers in the flight
control installation will detect turbulence phenomena and will provide for 1
instantaneous equalization by appropriate commands which would result in deflec-
tions of the wing. General Dynamics is working closely with the engine manu-
facturers in order to develop new noise suppression, technologies for the aircraft]
to be used between the years 1975 and 1985. Carline believes that the noise
level of aircraft engines can be lowered on the order of 50%. tcarline and NASA |
believe that long-range transport aircraft of the future will exceed present-day
aircraft in terms of flight performance, economy, safety, and comfort. At the
same time, they will produce less noise and poisonous substances than
conventional jets.
