Introduction Chapter 1
Parabolic flight is a useful tool for performing short duration scientific and
technological experiments in reduced gravity due to its short turnaround time, low cost,
flexible experiment approach, and direct on-board intervention possibilities.
Space agencies and industrial companies can benefit from a participation in a parabolic
flight campaign on the Airbus Zero-G in the following ways :
• Testing as part of a quality approach to manufacturing space hardware.
This is particularly true for mechanical parts (antenna and solar panel
deployment, hydromechanical system, etc.).
• Acquiring a better understanding of gravity in physical or physiological
phenomena for example.
• Gaining new insight into system’s safety and ergometric features
facilitated by in-situ observation by project engineers and scientists.
• Using the prestige associated with Zero-G flying as part of a marketing
strategy.
Introduction Chapter 1
Edition 5.2 1.2
Novespace offers two different flight configurations:
· Standard campaigns which consist of three flights of thirty parabolas
each on 3 consecutive days. Novespace can also accommodate several
different customers who can share the experiment cabin and the cost of
the campaign. The aircraft can accommodate more than a dozen
different experiments and between thirty and forty experimenters.
· Specialized campaigns can be customized to the desires and needs of
individual independent companies. These companies may decide on the
number of flights, the duration, and the profile of each flight. These
flights can depart either form Bordeaux or from any other airport in the
world.
In collaboration with the Centre d'Essais en Vol and Sogerma, Novespace is willing to
consider all demands of those interested in using parabolic flight services.

Parabolic Flight
Technique
2.1 Obtaining microgravity
A reduced gravity environment is obtained by flying a specially modified Airbus A300
Zero-G through a series of parabolic maneuvers which result in approx. twenty-two
seconds periods of « 0g » acceleration (actually around 10-2 g). Each parabola is
initiated with a 1.8 g pull up and terminated with a 1.8 g pull out.
A normal mission lasts two to three hours and consists of thirty parabolic maneuvers.
2.2 Description of the Parabolic Maneuver
Starting from a steady normal horizontal flight, the aircraft takes a 1.8 g load factor,
nosing up to 45° and climbing to 23 000 Ft over an interval of about twenty seconds.
This is the entry pull-up phase.
Then the engine thrust is considerably reduced, to the point where it just overcomes the
aerodynamic drag, and the pilot kills the lift. This transitory phase of "injection"
separating the 1.8 g pull-up from the zero g parabola lasts fewer than five seconds.

Edition 5.2 2.2
The aircraft is then in microgravity phase for some twenty-five seconds. A symmetrical
1.8g pullout phase is then executed on the down side of the parabola to bring the
aircraft back to its steady horizontal flight in about 20 seconds. There is an interval of
two minutes between two parabolas.
