Rocketdyne's E-1 was a liquid propellant rocket engine originally built as a backup design for the Titan I missile. While it was being developed, Heinz-Hermann Koelle at the Army Ballistic Missile Agency (ABMA) selected it as the primary engine for the rocket that would emerge as the Saturn I. In the end, the Titan went ahead with its primary engine, and the Saturn team decided to use the lower-thrust H-1 in order to speed development. The E-1 project was cancelled in 1959, but Rocketdyne's success with the design gave NASA confidence in Rocketdyne's ability to deliver the much larger F-1, which powered the first stage of the Saturn V missions to the Moon.

dbo:abstract
  • E-1 byl americký raketový motor na kapalné pohonné látky vyvinutý v padesátých letech dvacátého století firmou Rocketdyne. Původně byl vyvíjen jako záložní motor pro projekt rakety Titan a poté byl vybrán jako motor prvního stupně rakety Super-Jupiter, ze které se později stal Saturn I. Vývoj byl v roce 1959 zrušen, protože raketa SM-68 Titan byla vybavena motory LR-87 konkurenční firmy Aerojet a pro Saturn I by vybrán slabší motor H-1. NASA však byla s prací firmy Rocketdyne spokojena a udělila jí kontrakt na vývoj motoru F-1 pro Saturn V. E-1 byl velmi podobný motoru H-1. Oba byly vyvinuty z motoru , používaného na raketách Thor a Jupiter. E-1 však měl přibližně dvojnásobný tah. SM-68 Titan měl mít jeden motor a Saturn I měl být vybaven svazkem čtyř těchto motorů.

  • ロケットダインのE-1は元々はタイタンIミサイルの予備の設計として製造された液体燃料ロケットエンジンである。アメリカ陸軍弾道ミサイル局(ABMA)でHeinz-Hermann Koelleによって当時開発中だった後にサターンIとなるロケットの第一段エンジンとして選定された。結局、タイタンの第一段エンジンは計画通り(E-1は選ばれず)そのまま進められサターンには開発速度の為に低推力のH-1が採用された。 E-1計画は1959年に中止されたがロケットダインは設計においてNASAの信任を得る事に成功してロケットダインの能力は月へ向かうサターンVの動力となるより強力なF-1に適用された。 (ja)
  • O E-1 foi um motor de foguete de combustível líquido desenvolvido pela Rocketdyne, originalmente preparado para ser um desenho alternativo para o míssil Titan I. Enquanto ele estava sendo desenvolvido, na Army Ballistic Missile Agency, o selecionou como motor principal para o foguete que viria a se tornar o Saturno I. No final, o Titan continuou com seu motor original, e a equipe do Saturno decidiu usar um motor com empuxo menor, o H-1, para acelerar o desenvolvimento. O projeto do E-1 foi cancelado em 1959, mas o sucesso da Rocketdyne com o desenho, deu confiança à NASA na capacidade da empresa para fornecer um motor muito maior, o F-1, que equipou o primeiro estágio do Saturno V em seus voos em direção à Lua.
