operations make executing dedicated
flight tests essential. (Figure 1)
Today, computational fluid dynamics
(CFD) simulation software is used to estimate the trajectory of separation between
the aircraft and the store. But how reliable is the CFD model in real-life situations? To determine its accuracy, a flight
test campaign is used to measure the
store's actual separation trajectory. Several test points are selected from the
safest to the most extreme flying condition. The data sets collected from the test
flights will be compared against
the CFD simulation results to deter-

mine the safety level and readiness of the
store release operation.

The Mission
The Brazilian Air Force Flight Test and
Research Institute (Instituto de Pesquisas e
Ensaios em Voo; or " IPEV " ) is developing
an Optical Tracking System (SisTrO - " Sistema de Trajetografia Óptico " ) to measure
the store Time-Space Positioning Information (TSPI) during the test flight. The mission is to guarantee a safe store release
during the entire flight test campaign.

uring the release of an external store, such as a bomb,
from an aircraft, disturbances
in the airflow surrounding
the aircraft create coupled aerodynamic
loads. These loads affect the released
store's trajectory which may cause the
store to collide with the aircraft. Reducing the risk of such an event and ensuring the safety of
delivery, jettison, and
launch
