History
The development of RD-270 started in 26 June 1962 year. Preliminary investigations and development of engine as much as its further production was performed under the guidance of Valentin Glushko and finished in 1967. It became the most powerful engine in the world with use of high-boiling propellant to date. In the period 1967-1969, several fire tests were performed with experimental engines which were adapted for work at sea level and had short nozzle. Totally 27 fire tests were performed for 22 engines, three engines were tested twice and one of them was tested three times. All works stopped later together with corresponding activities on UR-700 project.
In the period of development Glushko studied use of pentaborane 'zip' propellants in modified RD-270M engine. This would have created immense toxicity problems but increased the specific impulse of the engine by 42 seconds.

Famous quotes containing the word history:
“The greatest horrors in the history of mankind are not due to the ambition of the Napoleons or the vengeance of the Agamemnons, but to the doctrinaire philosophers. The theories of the sentimentalist Rousseau inspired the integrity of the passionless Robespierre. The cold-blooded calculations of Karl Marx led to the judicial and business-like operations of the Cheka.”
—Aleister Crowley (1875–1947)
“The visual is sorely undervalued in modern scholarship. Art history has attained only a fraction of the conceptual sophistication of literary criticism.... Drunk with self-love, criticism has hugely overestimated the centrality of language to western culture. It has failed to see the electrifying sign language of images.”
—Camille Paglia (b. 1947)
