Because the new propellant provides improved performance and volumetric efficiency compared to hydrazine
, more of it can be stored in propellant tanks of the same volume, resulting in a 50-percent increase in spacecraft maneuvering capability for a given volume.
The study provides a decisive view of the global hydrazine
hydrate market by segmenting it in terms of end-user segments.
Therefore we decided to use for the preparation of aza-Phe, aza-Tyr, and aza-Trp precursors another known synthetic pathway, which includes direct A-alkylation of protected hydrazine
with appropriate alkyl halides (Scheme 1, right side).
If verified as a valid alternative, this new propellant could be used not only in spacecraft, but also in military vehicles that operate on hydrazine
, said Roger Myers, executive director of Aerojet Rocketdyne, a partner in the program.
For anyone wondering what it actually is, it's likely a 39-litre hydrazine
bladder tank (based on its apparent size; there are also much larger hydrazine
The recent reports on severe hydrazine
poisoning indicate that swallowing about 20-50 ml of hydrazine
can prove to be fatal.
sulfate trials involving cancer patients were performed in Russia (then the Soviet Union) and by researchers at Harbor-UCLA Medical Center during the 1970s and 1980s.
The Pentagon feared that a satellite that size would not burn up upon re-entry, and could scatter debris - including hydrazine
- in inhabited areas.
But it is carrying more than 1,000lb of hydrazine
fuel and may release much of it as a toxic gas.
The satellite has thrusters, small engines used to position it in space, that contain the toxic rocket fuel hydrazine
Only a few references are available regarding either the formation of ketazines or for the production of hydrazine
hydrate through ketazine route, mainly using hydrogen peroxide including patents (Eichenhofer and Sehliebs, 1976, 1977; Schirmann et al.
The technology, proposed by engineers at Daihatsu, a unit of Toyota, in Ryuo, Japan, uses a fuel called hydrazine
hydrate, instead of hydrogen.
