Lockheed Martin X Description. Lang: en The Lockheed Martin X was an uncrewed, sub-scale technology demonstrator suborbital spaceplane developed in the s under the U.S. government-funded Space Launch Initiative program. Aug 07, · You are absolutely correct in pointing out the severe problems we have at KSC regarding the infrastructure, but you take a leap of faith that says for next generation RLVs, current concerns about KSC will not matter much because the new vehicle will be or should essentially be Single Stage to Orbit (SSTO).
Airport to Orbit, A Comparison of Horizontal Takeoff RLVs. (SSTO) rocket vehicle and a TSTO spaceplane without built-in growth. Book explains why we were never able to colonize space. The challenge is not building these RLVs; the challenge is getting them financed. Wall Street is rightly skeptical, given the history of broken promises about low-cost launchers. My experience in the private and government sectors is that financing on Wall Street, or acceptance at the Pentagon, cannot be won with viewgraphs.
Mar 31, · As an intern, he worked on several projects, including the Space Shuttle External Fuel Tank and X, an early prototype of single-stage-to-orbit reusable launch vehicles (SSTO RLVs). At the end of the summer, Marc transferred to the University of New Orleans so that he could work part-time at Lockheed Martin.

Apr 26, · Bahn’s conclusion was stridently disputed by some in attendance, notably Jerry Pournelle, a famous science fiction writer and a long-time advocate of DC-X and other single stage to orbit (SSTO) technologies.
One must admit, though, that the path towards low-cost RLVs, and SSTO vehicles in particular, has been a rocky one. The Lockheed Martin X was an uncrewed, sub-scale technology demonstrator suborbital spaceplane developed in the s under the U.S. government-funded Space Launch Initiative program.
The X was a technology demonstrator for the VentureStar orbital spaceplane, which was planned to be a next-generation, commercially operated reusable launch akikopavolka.comon: Uncrewed re-usable spaceplane.

The National Academies Press. doi: / Efforts to validate the analysis SSTO RLVs book and scaleability to SSTO RLVs are progressing in a reasonable direction.
Extensive subscale tests, moving from coupon size through. E Selected Reusable Launch Vehicle Development History. The fundamental ideas underlying reusable vehicle concepts, such as the reusable booster system (RBS), are not new, and many significant activities have been conducted in both the United States and overseas that are aimed at realizing the potential gains that come with reusability.
The X would flight-test a range of technologies that NASA deemed critical for SSTO RLVs, such as the aerospike engine, metallic thermal protection system (TPS), and its lifting body aerodynamics.
The X was intended to be a low-cost testbed for demonstrating RLV key technologies. It was conceived to be an autonomous pilotless craft Author: Antonio Viviani, Giuseppe Pezzella.
My argument against most SSTO approaches is more a pragmatic one than a dogmatic one. Namely, while SSTO RLVs aren’t impossible they are premature. Other than the airlaunched “assisted SSTO” concept, I don’t think any of the other SSTO RLV approaches are close enough to our current state of the art to be worth trying at this point.
What has been lacking is the tri-propellant propulsion technology for SSTO-RLVs. Entrepreneurial firms, such as TGV, have proposed novel approaches to the challenges of an SSTO-RLV. These innovations include new ways of approaching a tri-propellant engine, novel engine nozzles for altitude compensation, and new launch sites for more flexibility.
Judged solely on its merits as a novel the book would be considered very poor, but in reality the story serves as a vessel to communicate the merits of a particular TSTO RLV design. One could strip out the fictional elements and instead have a straightforward engineering treatise about RLVs, but that arguably would be less entertaining to read.
Reusable Launch Vehicles. The last decade of the second millennium saw the emergence of the idea of sending payloads into space with reusable launch vehicles (RLVs). It appeared to make economic sense to reuse a launch vehicle that cost as much as a small.
Before I get into pointing out the flaws I saw on Mark Whittington’s blog the other day, I need to lay a little groundwork. A few weeks ago, I got an email from one of the coauthors of an interesting new book, The Rocket akikopavolka.com of the chapters from the book were initially released on akikopavolka.com about a year ago as a serial.
The paradigm change in space launch vehicle design and operation - from performance optimization to minimum cost strategy - has greatly increased the importance of cost engineering. This is even more important for the future generation of reusable launch vehicles (RLVs) due to the relatively high development akikopavolka.com: D.
Koelle. Mar 21, · It works, but it’s not very efficient, to say the least. This is why research has been turning towards SSTO RLVs, or “single-stage-to-orbit reusable launch vehicles” – spacecraft that resemble typical aircraft more than the bulky shuttle design we’ve been using for so long.
Jun 10, · We’ve spent years chasing the idea of “cheap access to space”, and we never actually understood what that meant. We assumed that it was a purely technical problem. The solution to cheap access will be a reusable vehicle (space shuttle), will be scramjets (NASP), will be SSTO.
I am somewhat out of touch with the latest developments, but last I heard some small funding was being made for basic R&D on advanced reusable engines, reentry and GNC.
Namely, the Volga and Veda engines, EXPERT and PRE-X for reentry, EADS Phoenix for GNC. AFAIK there is no concrete plan for a reusable vehicle. Jun 10, · One varient of the idea I was thinking of involved two RLVs in earth orbit, with one acting as a booster.
which might aleviate the payload fraction and solve the throttling problems in some designs. One book I read (The Rocket Company) said lunar surface costs would be 6x LEO costs for an arbitrarily reusable vehicle.
SSTO isn't easy to. Charge I. Opponents claim that SSTO RLVs could not carry the significant number of DOD, NASA, and commercial payloads bound for geostationary orbit (22, miles equatorial orbit) since the NASA SSTO reference configuration is designed to carry a 25, lb.
payload to the planned international space station orbit at just nautical miles. NASA Administrator Calls for Space Privatization The role of business will be to fill niche markets and routine work such as SSTO RLVs.
The focus of government and public organizations should be on the programs that open the niche market, leverage techonolgies such as RBCCs (Yes I am a fan of RBCCs for the simple reason that they have 1/5().
Launch. Recover. Repeat. Elon Musk’s Company SpaceX started with an attempt to recover the first stage of its Falcon 9 rocket. If it succeeds—enough has been demonstrated so far to make that likely—SpaceX will become the first to launch a rocket-powered first stage to orbit, then land it.
Nov 09, · As has been pointed out above, most SSTO projects do not stack up against TSTO based on how much vehicle is required given the same technology of SSTO vs TSTO.
So what would change that picture. Well changing the ISP is the first thing that comes to mind, no mater what we do it is the place where you get the biggest bang for your buck. Gary Hudson wanted to go for a real spaceship.
One that you just get into, takeoff vertically, and go to orbit. such as a book. Short answer is yes, there are many things. Everything is so tightly interlocked on RLVs, especially SSTO designs. Although propulsion and low mass structures are obviously crucial, is the toughest challenge of.
In fact, making RLVs that have the characteristics of airplane operations is the essence of the revolution in thinking behind reusable launchers, that is, true spaceships. Today, I want to use the story of the SDIO SSTO Program to draw some conclusions about what has been the driver, the "force motrice," behind the search for reusability.29 July Added "Space Debris and Its Mitigation" to the archive July Space Future has been on something of a hiatus of late.
With the concept of Space Tourism steadily increasing in acceptance, and the advances of commercial space, much of our purpose could be said to be achieved.You are absolutely correct in pointing out the severe problems we have at KSC regarding the infrastructure, but you take a leap of faith that says for next generation RLVs, current concerns about KSC will not matter much because the new vehicle will be or should essentially be Single Stage to Orbit (SSTO).
