rocket engine. It was designed to power a third stage of newly constructed <a href="/wiki/Ariane_1" title="Ariane 1">Ariane 1</a>, the first launch system for <a href="/wiki/European_Space_Agency" title="European Space Agency">European Space Agency</a>. Maiden flight took place on 24 December 1979 successfully placing <a href="/wiki/CAT-1" title="CAT-1">CAT-1</a> satellite on the orbit. With the later introduction of <a href="/wiki/Ariane_2" title="Ariane 2">Ariane 2</a> and <a href="/wiki/Ariane_3" title="Ariane 3">Ariane 3</a> it became necessary to improve the performance of the upper stage engine. This was achieved by extending the nozzle length and increasing the chamber pressure from 30 to 35 <a href="/wiki/Bar_(unit)" title="Bar (unit)">bar</a>, increasing the engine's <a href="/wiki/Specific_impulse" title="Specific impulse">specific impulse</a> and resulting in a nominal burn time increase from 570 to 735 seconds. Qualification tests were completed in 1983 and this upgraded variant was designated HM7B. It was also used on the Ariane 4 vehicle's upper stage where the burn time was further increased to 780 seconds, and since 12 February 2005 it's also used on the upper stage of <a href="/wiki/Ariane_5" title="Ariane 5">Ariane 5</a> ECA.<sup id="cite_ref-AirbusChamber_2-1" class="reference"><a href="#cite_note-AirbusChamber-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Overview">Overview</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=HM7B&action=edit&section=2" title="Edit section: Overview"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The HM7B is a <a href="/wiki/Regenerative_cooling_(rocket)" class="mw-redirect" title="Regenerative cooling (rocket)">regeneratively cooled</a> <a href="/wiki/Gas-generator_cycle" title="Gas-generator cycle">gas generator</a> rocket engine fed with <a href="/wiki/Liquid_oxygen" title="Liquid oxygen">liquid oxygen</a> and <a href="/wiki/Liquid_hydrogen" title="Liquid hydrogen">liquid hydrogen</a>.
