Brazil: IAE Conducts VLS Qualification Tests

IAE PR — The Aeronautics and Space Institute (IAE) has successfully, the test of separation of the four engines of the first stage of the Satellite Launching Vehicle (VLS). The event was successful and simulated a situation that will occur about 32 km altitude when the vehicle is in flight. The test was carried out yesterday (29/09) in the laboratory of Integration of the IAE propellants and had a team of 45 technicians and engineers between servers. The main objective was the qualification system of separation of the first stage of the VLS.

In total, 167 measurements were made from mechanical shock, vibration, quasi-static deformation, pressure, displacement, separation symmetry, as well as photo coverage, video (HD and high speed). The data collected will be analyzed and used as a basis for understanding the phenomena occurring in the vehicle during this important phase of flight. Among these phenomena are the simultaneous ejection of the engines, the tensions at the interfaces between the second and third stage and mechanical shock loads in the central body and embedded devices. Will also made a comparison between the signals acquired with the telemetry system and ground systems, an important procedure for the qualification of the measurement system in flight.

The VLS is capable of putting into orbit a satellite of 115 kg at 750 km altitude. The vehicle is separated into subdivisions, which include four stages, and ejection Hood, Power Lines and Networks Pyrotechnics.
