Your objections suggest what I propose cannot work. You fail to say why specifically you believe this to be so. Others have not been proven on a launch vehicle in the actual conditions experienced by a launch vehicle. * The entire system is well thought out and quite workable.

Not a tootbrush. Do you imagine that some things might be a little complex for such a vehicle? Of course you do. So, what is your beef dude? What is wrong with putting the shocks and other stuff into the landing platform to save weight on the rocket? Specifically what is unworkable about it? Especially given the fact that advanced automation exists that can easily track the descending vehicle and stay under it. which is intended to catch your landing rocket stage and balance it like a Segway). Not *exactly* like a Segway - but close. The fact that you can't see how "far out" your "design" really is speaks volumes. What is far out about using External Tank sized air frames in parallel staging? What is far out about a multi-stage rocket? What is far out about ballistic re-entry and downrange recovery without a bunch of pointless and difficult aerial maneuvers? What is far out about a tow plane snagging a glider during descent?

In what way is it fundamentally unlike any launch vehicle ever flown? It uses parallel staging of External Tank sized airframes equipped with cross-feeding. The space shuttle has used parallel staging of External Tank sized airframe equipped with cross-feeding for the past 40 years. So, what's up with your objection? *It's up to you to prove to the world it will work. I have done that. I've given you the numbers, they are accurate and resonable http://www.scribd.com/doc/31261680/Etdhlrlv-Addendum Seven 49.5 tonne air frames carrying 730 tonnes of propellant with exhaust velocity ranging from 4,358 m/sec to 4,541 m/sec as the aerospike engines ascend through the atmosphere along Goddard trajectory achieves an ideal delta vee of 9.2 km/sec a delta vee matched by the Space Shuttle, while carrying 632 metric tons of payload. *It's not up to the world to prove that it won't. * If I give ample evidence that a thing will work, and anyone says in the face of that evidence that it doesn't work, then they've got to tell me what it is they think stands in the way of it working. You are the one saying it won't work. I am just asking to state why? You have a reason don't you? The hand waving and bull**** you've trotted out thus far doesn't stand up to scrutiny. You claim to be an engineer, prove it. Show me where my numbers are wrong and back it up with solid evidence. You haven't done that. You've only engaged in baseless innuendo. So far your proof has been sorely lacking, IMHO. Lacking in what way? But your mileage may vary and you may yet attract investors. That depends on what my vendor group says and their background more than anything I say. *Good luck with that. * Yeah, haha, I can feel the love. NOT! lol. History is littered with failed launch start ups So? History is also filled with systems that have succeeded. with vehicle designs far less ambitious than what you propose. In what way is the system ambitious? The ET is already flying. The RS-68 is already operational. Aerospike engines have been built in the 9 million lbf thrust range. We're only looking at 2.2 million lbf thrust. So, how is this ambitious? Then, how does that ambition specifically translate to risk? And how is that risk irreducible by a well thought out development test flight program? Jeff -- The only decision you'll have to make is Who goes in after the snake in the morning? Like I said, a $50 million investment starts with a $4.5 million flight element using a single RL-10 pump - producing 18,000 lbf - similar to the AMPS-1 engine, but not using the exotic propellants. The 1,800 lb airframe will carry up to 12,600 lbs of propellant that's 5.5 ft in diameter and less than 32 ft long. This reusable flight element allows a wide range of flight speeds and builds upon the computer and wind tunnel modeling already done. The development of a second flight element attains orbit. The operation of seven flight elements allows 5,575 lbs to be placed on orbit and testing of the entire flight vehicle concept. 14 flight elements built for $50 million provides a very flexible range of flight capabilities up to 5,525 lbs, and at $10,000 per lb on orbit, along with high reliability, self insurance, and quick response, earns $55.25 million per launch and 30 flights per year - only 25% of the world's total demand for space launch in this size range - this company has a greater free cash flow than Boeing each year! Achieving this level of success, provides a means to build a larger vehicle that lifts 77,000 pounds into LEO using the same process. This vehicle supports the deployment of 800+ comsats that are networked on orbit by open optical peta bit laser beam, and are launched by this vehicle two at a time. This creates a network of satellites that once operating produces a free cash flow 100x that of Boeing! Achieving this level of success provides a means to build an even larger vehicle, the one described, with over 1.56 million pounds into LEO, this vehicle deploys 17,058 ft diameter power satellite that beams 10,000 MW to 8,000 ground stations (at 1.25 MW each) simultaneously - earning twice the free cash flow of Boeing PER SATELLITE! The world presently uses energy at a rate of 17 million MW and that is growing at 680,000 MW per year. So, 68 satellites PER YEAR at 10,000 MW each, would just meet today's demand. 136 satellites would displace conventional fuels at a rate of 4% per year. The wealth of the oil rich kingdoms would flow into our companies coffers at this level of success. |

But your mileage may vary and you may yet attract investors. *Good luck with that. *History is littered with failed launch start ups with vehicle designs far less ambitious than what you propose. Has anyone ever used a tow plane to grab onto a glider as it descended? Yes. I can't think of a case of that being done. Typically gliders are launched with tow planes, not grabbed after being released. But, with the right equipment it can be done, and has been done in test. Its not that hard. You can snag parachutes on a descending space capsule with an aircraft; Yes, and if you look at the rate of descent and maneuverability of the parachute relative to the glider, its a far harder thing to do. So, since that has already been done with 1950s guidance technology, for parachutes, its a slam dunk certainty that a glider guided by GPS signals can be picked up by a far faster aircraft also guided by GPS signals - with wireless networking operating between the two aircraft. that was the standard method of grabbing spy satellite film return capsules. Correct and if you look at the primitive methods used to track the capsule and bring the capsule to the aircraft, if you look at the rate of descent of a parachute versus a glider, if you look at the controllability of an aircraft versus a parachute, if you look at the methods of communication guidance and control available today, and if you look at the speed and range of a Boeing 737 versus a C-119 its an absolute certainty that gliders can be retrieved far more easily than the Corona capsules ever were. But hooking on to a glider in flight would be difficult to do. No it isn't. Drop a tow line from the nose of the glider aircraft and a harness from the tail of the pick up aircraft and fly the harness beneath the glider - as the pick up aircraft flies bove - snagging the tow line with the harness - and then apply power to the pick up aircraft to maintain altitude of both craft once locked together. Then when over the landing threshold release one end of the harness line - which looks like a 'U' in flight - which releases the two aircraft (the other side of the harness line may also be released if there is a problem - as well as the tow line) The lines are retracted and the glider glides in for a landing as described as the tow plane lands at a separate airfield. You would have to fly above it or ahead of it and figure out some way to attach to it with a line or boom of some sort. We've already done it and done it with gliders and small aircraft. So, its not that hard. Pat |
