Hi,

I never saw like this concept exactly,a variable-geometry reentry.

You guys might like some of these pics. Some of those pics seem pretty new to me. Probably because I've never seen them before! :-D

The shots of the X-24A being converted to the B configuration are worth a gander.

Recently posted on YouTube by NASA Armstrong Flight Research Center (Edwards AFB), December 12, 1969 footage of the remote controlled flight (piloted by Milt Thompson on the ground) of the Hyper III, after being dropped from altitude by a "borrowed" US Navy Sikorsky SH-3 Sea King helicopter (piloted by Bruce Peterson).

That's Convair version of reusable Atlas rocket
the reusable Second stage is a lifting body

From L+K 12/1965,

I don't remember what was this Boeing ?.

The idea is intriguing: Aero-Gravity Assist

Do a Fly-By so close to Mars and Venus, that the Spacecraft rams through its atmosphere at hypersonic speeds.
The study look into use of Waverider (Lifting Body) cover in Carbon heatshield to survive the temperature of 3000°K
According the Study it would reduce travel time to outer Solarsystem
Bonus the Waverider could use Aerodynamic capture at target Gas giants or Saturn Moon Titan

Interesting stuff! I recall ASTRA (Association in Scotland to Research into Astronautics) proposed a similar mission plan for an Interplanetary Waverider around the same-ish time. Up to and including a 'flexible' aero-form for more utility. Can't find my good link :(

Some more Interplanetary Waverider stuff I came across:


[/URL]

Among others :) There appears to have been a couple of waves, (pardon the pun) of interest around the late 90s and mid-2000's for some reason.

Oh and this one is interesting both in the historic and conclusions on 'wedge' waveriders:

Oh I remember seeing that. The most insane aerobraking concept ever. They hoped to be able to go into a retrograde orbit around the sun (or fall into it, solar probe style) by flying around Venus using Venus's atmosphere.

Per lack of a better thread...
The FDL-5 / L-301 / Model 176 family - gimme a break... I just red (I will link the papers later) that
- Lockheed build a halfscale FDL-5MA mockup in 1969
- the final vehicle was to have an aerospike (http://www.astronautix.com/a/amps-1.html)
- with LH2/ fluorine and ISP 468 seconds
- enough to haul itself into orbit with a pair of drop tanks (with a classic Titan III as a more reasonable alternative)
- and that L-301 inspired Lockheed Starclipper own V-tanks

My mind is completely blown. Please help clearing what is fantasy from what was real. Is that aerospike thing any serious ? and fluorine, for frack sake ? God help the unfortunate pilot...

The LF2 engine was part of a three-prong effort led by the Air Force Rocket Propulsion Laboratory in the mid-1960s. The other projects were a reusable storable-propellant upper stage and the XLR-129.

Very interesting... XLR-129 was SSME ancestor and even early contender, plus ISINGLASS engine. So these two were related ? does this mean that ISINGLASS and FDL-5MA were related, too ? ISINGLASS also produced some hardware rather than paperware, since some kind of test article was build.

a reusable storable-propellant upper stage

Any more information ? considering the pedigree of the other two, this one might be interesting.

Lockheed won the Reusable Subsystems Design/Analysis study, covering three military space applications:
  • Project 1: Reusable upper stage
  • Project 2: Manned reusable launch vehicle, 25K lbm payload (ancestor of the Lockheed Star Clipper)
  • Project 3: FDL-influenced manned reusable spaceplane
The project 1 vehicle was dropped early on and its propulsion system was studied as an alternative (for obvious reasons) for the project 3 vehicle. The associated AFRPL propulsion systems and contractors were:
  • Project 1: N204/Hydrazine-50 -- Aerojet MIST
  • Project 2: LO2/LH2 -- Pratt & Whitney XLR-129-P-1
  • Project 3: LF2/LH2 -- Rocketdyne AMPS engine (one of many aerospike config studies by Rocketdyne in the 1960s)
Exec summary of the program (with the alternative propulsion options for vehicle 3) is here:

Same engine ? MIST is mentioned.


A US staged combustion storable props engine - that would be much like the Soviet / Russian Briz-M engine (whatever its name) or RD-270 no ?

Not sure -- both the USAF and NASA funded a lot of prototype engines of all types in the 1960s. There were at least four Rocketdyne aerospike programs in those days, for example, but presumably fundamental technology was shared among them.
