CAD Program Helps Reduce Costs
When it comes to designing aircraft
of any type, one concern that every company boss will tell you
about is that it's not only very expensive to design airplanes but
it can take too long to complete. And these days, cost reduction
and being first to market are important factors in aviation.
There are a lot of CAD design software tools available to let
the design department's imagination go wild... but comparatively
few products on the market that will actually help you discover if
your aircraft will actually fly, and have any sort of stability and
control before going to the expensive stage of wind tunnel
The J2 Universal Tool Kit from J2 Aircraft Dynamics is the only
off-the-shelf and commercially available software product that can
do this effectively. This software makes no assumption as to the
type of design and will allow any sort of configuration.
There are no restrictions to the wing design, airframe size or
propulsion system -- everything can be modelled very quickly,
according to company officials. The aircraft's performance,
stability and control can be assessed and an accurate virtual video
flight is displayed on screen in a real environment.
The software will allow you to make multiple design
modifications 'on-screen' with just a few clicks of the mouse and
then re-fly the changed aircraft and have them perform defined
flights like take-off, in-flight maneuvers and landings. You are
even able to set-up flights to conform to FAA regulations and be
sure your aircraft will pass these regulations 'first-time'. This
method is not only very quick but it saves a lot of money because
the aircraft Company no longer has to build multiple physical
models with the different changes to see how they perform or
complete many flight trials to modify or change the design.
The J2 Universal Toolkit also allows exploration of factors like
the effects of gusting, ground effect, propwash, changes in CG and
mass and inertia to name but a few.
