  • Ariane 6 launch pad water deluge system test

    Ariane 6 launch pad water deluge system test

    The water deluge system, which is activated at liftoff, was put to the test on the Ariane 6 launch pad at Europe’s Spaceport in April 2021. This is one of the qualification tests to prepare for the arrival of Ariane 6, Europe’s next generation heavy-lift launch vehicle.

    Spraying huge volumes of water on the launch pad and beneath the launch table protects both the launch vehicle and its payloads by absorbing and deflecting the tremendous acoustic energy generated at liftoff. Shockwaves created as engine exhaust gases exceed the speed of sound and collide with ambient air cause noise levels to reach 180 decibels.

    Three areas are deluged with water during launch, this is done in sequence.

    At 20 seconds before liftoff, water sprays over the steel deflector 25 metres below the launch table. This deflector channels the engine exhaust into the two trenches.

    At 6 seconds before liftoff, the exhaust tunnel under the launch table is deluged. This channels the engine exhaust below the launch table and into the underground trenches leading away from the launch pad.

    Finally, as Ariane 6 lifts off the ground four arrays of pipes around the sides of the launch table will flood the launch pad.

    This water also serves to cool and protect the ground installations, mainly the steel launch table.

    About 700 cubic metres of water will be released during launch. This comes from the nearby tower which holds 1200 cubic metres of water. After launch it is refilled with water from a nearby lake.

    After launch, any remaining water below the launch table is pumped away.

  • Pad Abort Test of Boeing’s Starliner Spacecraft, Nov. 4, 2019

    Pad Abort Test of Boeing’s Starliner Spacecraft, Nov. 4, 2019

    TESTING 1…2…3🚀 Boeing put its #Starliner’s launch abort system to the test on Monday, Nov. 4 at the White Sands Missile Range in New Mexico, lifting off at 9:15 a.m. EST. The test demonstrated the spacecraft’s ability to protect Commercial Crew Program astronauts by carrying them safely away from the launch pad in the unlikely event of an emergency prior to liftoff.

  • Launch Pad Water Deluge System Test at NASA Kennedy Space Center

    Launch Pad Water Deluge System Test at NASA Kennedy Space Center

    This system is used to reduce extreme heat and energy generated by a rocket launch.🚀 On Oct. 15, 2018, the Ignition Overpressure Protection and Sound Suppression water deluge system at Kennedy Space Center’s Launch Pad 39B was tested, sending water about 100 feet in the air. The test is part of preparation for launching our Space Launch System rocket on Exploration Mission-1 and subsequent missions.

    Modifications were made to the pad after a previous wet flow test, increasing the performance of the system. During launch, this water deluge system will release approximately 450,000 gallons of water across the mobile launcher and Flame Deflector.

    The family of European rockets is growing. The next one is the youngest, called Vega, soon to be launched from Europe’s Spaceport in French Guiana.
    This new rocket complements the range that Europe already has to offer in the commercial market.

    NASA’s Mobile Launcher Moved to Launch Pad

    The mobile launcher that’ll support NASA’s Space Launch System (SLS) has moved from the Vehicle Assembly Building to Launch Pad 39B at the Kennedy Space Center in Florida. The 355-foot-tall ML, which took about two years to construct, is
    being modified to support the heavy-lift rocket that will launch astronauts farther into space than ever before. SLS also will create high-quality jobs here at home, and provide the cornerstone for America’s future human space exploration efforts.
