rocket propulsion

The general rule of hard sci-fi is that there is no (easy) stealth in space, and I'm perfectly content with it. What I have some troubles with, is that this rule include decoys, too. I like decoys) So I brainstormed quite a long time, and came with the idea of drive system, that - theoretically...

Found these in the Spanish online patent repository in the aircraft related patent clasif. it was hard for me at first to understand the design as i havent seen much aircraft like this before but it has retractable blades on the side of the plane that spins like a helicopter to make vertical...

Hi there, in interrogation report Larsson et al, Ref. No. SAIC/38, NARA, the following statement can be found: Did anybody of the researchers come across such a system? Kind regards, Manuel

Hi again after long while. I recently finished some new 3d pieces so I thought I may drop these by. Below my latest (and some older) artwork for IJN's Mizuno Shinryū II. If you feel like it, look up more on https://www.artstation.com/senshi-isamu or https://www.deviantart.com/senshi-isamu. Cheers!

A couple new books are on pre-order at Amazon.co.uk: https://www.amazon.com/Fighters-1945-Secret-Projects-Luftwaffe/dp/1911658085/ref=sr_1_1?qid=1563554467&refinements=p_27%3ADan+Sharp&s=books&sr=1-1&text=Dan+Sharp...

1980's paper on the 'ultimate rocket fuel'... http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19820013176.pdf

A two stage program to test the linear aerospike concept, the first test bed proved the basic concept, the second test bed explored the use of thrust vectoring. Linear test bed. Volume 1: Test bed no. 1. (Aerospike test bed with segmented combustor)...

...So, was this part of an Air Farce project into larger solids for the Titan III series, or were there "clandestine" tests done on SRBs for the Saturns? http://www.mandatory.com/2012/10/04/a-giant-un-used-nasa-rocket-has-been-sitting-underground-for-50/?ncid=txtlnkusaolp00000058

During the 1960's NASA looked at several possible improvements to the existing Block II Apollo's. One such study was by Bell and looked into a new design for RCS thrusters, which was theoretically scaleable from 5lb to 1000lb of thrust. Experimental auxiliary rocket engine, part I. Final report...

Just uploaded to the NTRS, a rather interesting study from the late 1960's The Aerospike Engine. Concept, Performance, Design & Operational Data. Liquid Hydrogen Propellants 250-500 KBLF Thrust Class http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19900066185_1990066185.pdf

in 1964 NASA start improve the performance of the J-2 first under projectname "J-2X" later rename to J-2S they test fired Engine between 1965 and 1972, with in total of 30858 seconds burn time. Major difference J-2 between J-2S are: -the gas generator cycle to a tap-off cycle that supplied hot...

This Aerojet-General report from 1964 discusses the possible future evolution of liquid oxygen / liquid hydrogen -fueled rocket engines from 1966 to 1986. From the M-1 rocket engine to the notional Advanced Engine, Ducted Rocket, and then Advanced Air Cycle for post Saturn launch vehicle...

The Aerojet-General M-1 was the largest and most powerful liquid hydrogen-fueled rocket engine to be designed and built. It offered a baseline thrust of 1.5 million pounds force and 1.8 million pounds force as its immediate growth target. The M-1 was larger and produced more thrust than the...

I found in Robert L. Forward novel "Saturn Rukh" this Synthetic Fuel: metastabil Helium NHe64* know someone about this is a real proposal or is this pure Sci-Fi ? (Forward had Habit to put proposals in his novels) the idea of metastable helium is this: Three helium atoms are aligned in a...
