t/Space Demonstrates New Air-Launch Method 117

FleaPlus writes "Last month t/Space, an organization with plans for constructing a simple, low-cost successor to the Space Shuttle, was mentioned on Slashdot. Recently t/Space used a portion of the concept study funds it had been awarded by NASA to also build and test actual hardware. They performed three weeks of drop tests of a 23%-scale model from a Scaled Composites Proteus carrier aircraft to demonstrate the feasibility of a new air launch method they had devised, dubbed 'Trapeze-Lanyard Air Drop.' The new method eliminates the need for wings on air-launched rockets, potentially leading to improved safety and cost-effectiveness. Last month at a space conference they also displayed a full-scale model of their vehicle. Unfortunately, with the recent selection of Boeing/Northrop-Grumman and Lockheed-Martin as the two competing teams for the contract to build the Shuttle's successor, t/Space's future path is somewhat uncertain."

      And the abort mode for a stuck cable or bad chute is....? :)

      Not that it's not an interesting deployment concept, mind you. There are lots of interesting airbreathing assisted methods, although none of them scale up to very large orbital craft. In addition to this and standard belly-dropped rockets, there's also wing-dropped (doesn't usually need a custom aircraft, but is geometrically constrained and offbalances the craft), roof-launched (the whole "tail" thing tends to get in the way unless you have a custom craft, but you can handle almost any geometry), tow-launch (you pay a penalty in carrying heavy landing gear, but the modifications to the towing craft are minimal), unfuelled tow launch (you fuel midair from lines attached to the craft at liftoff), docking and fuelling (taking off with just enough fuel to get to altitude - allows for multiple reentries and possibly powered landing), and carrying the craft inside the carrier, launching with a drogue chute (very geometrically constraining, but almost no modifications to the carrier needed).

      The problem with scaling up is that airplanes get tougher to scale up beyond a point. It's really only realistic for small satellites and humans to LEO.
      • It's really only realistic for small satellites and humans to LEO.
        Human craft tend to be relatively big and heavy? Did you mean to implyl "and small humans" to orbit?

        I seem to recall reading some speculation that a spacefareing race would evolve to be smaller.
        • ?

          No. I didn't think my phrasing was hard to understand, but let me rephrase:

          It's really only realistic for humans and small satellites to LEO

          A craft carrying, say, three people will have only, perhaps, 300kg of human cargo (plus life support, backup systems, supplies, etc). Many satellites are even smaller than the human portion of the mass alone. Large satellites, probes, and modules for things like ISS, however, are often measured in metric tonnes and are physically quite large.
      • tow-launch (you pay a penalty in carrying heavy landing gear, but the modifications to the towing craft are minimal)

        The spacecraft does need some kind of landing gear, unless a disposable sled is used for takeoff. Consider a cart strapped to the vehicle and dropped at liftoff

        But the real problem is that the spacecraft has to fly from the word go, and (unless we assume your next option) needs to do so fully fuled.

        This works surprisingly well for sailplanes but spacraft have the opposite problem. They are

        • The heavier the craft at takeoff, the stronger (and thus heavier) the landing gear that you need. The big mass elements of a spacecraft are its tanks and any structural support; the landing gear is a critical structural support. When you factor in that even a couple kilograms extra mass at takeoff will cost you dozens of kilograms of payload, it makes a huge difference.
          • You don't need landing gear in orbit hell you don't need them above 50 feet so you could easly have 2 sets the "fuel tank empty we are back from orbit type" and the "we need to get off the runway type" which could fall off. Using a system like this much of the weight at takeoff need not go above 50 feet in the air which means the fuel costs are vary minimal.
      • It's really only realistic for small satellites and humans to LEO.

        And a net in LEO to catch the humans.

      • You can air launch a pretty good sized vehical. A 747-400F can lift over 120,000kg A mission specific aircraft could probably do much better.
        I don't know about manned but for sats it may be the way to go.
        • Which means you can put 5-10,0000 kg in LEO, depending upon how good your rocket guys are. Which is decent. But chances are you are going to have to structurally reinforce that 747-400F to carry the rocket, which will reduce the weight, etc... its a system of trades. But even still no reason it couldn't be used as a launch platform for an ISS ferry vehicle.

          The downside is, now you are launching from a moving platform. And the savings, while there are some, arent **that** great... IE, you aren't going to b
        • Should be able to put it into a relatively gentle parabola and simply kick your 56.7t load out the tail.

          Computers have been halving in cost for the same power every 3 years for most of the past century. Rockets have hardly dropped in price since the 1960s, *despite* the increased amount of private industry development. Despite the satellite boom of the 1990s. Etc.

          PCs kept dropping in price because simpler (and higher power) manufacturing techniques kept being developed - and there was a clear path layed out for the next decade at almost all times, with research laying clear foundations for the every-three-year doublings of the next several decades. Nothing even close to this exists for rocketry. The only major thing that can do an order-of-magnitude reduction in prices are huge materials leaps forward (we'll get incremental improvements, of course - there's some nice ones due soon).

          How about air travel in the 40's and 50's?

          Driven almost entirely by people who needed to travel, paying the equivalent of several thousand dollars per ticket (not several hundred thousand), and getting to a destination that they had a strong need to arrive at. Very little of it was "joy riding", even if travelling places by plane was somewhat of a status symbol.

          Give commercial space travel it's start

          Private industry developed almost everything NASA ever built. Private companies like SeaLaunch and Orbital successfully built their own privately funded rockets; there was no leap forward, just incremental improvements. Several dozen companies outrght failed. It's not a "private industry" thing; it's a "technology thing". And no, a rocket that goes a tiny fraction of orbital velocity isn't a step forward; it's a big leap backwards. If you're going to hawk a "private enterprise" technology with promise, you should be hawking SpaceX or whatnot. The "100km straight up and then down" companies are as close to real space travel as a person who makes a go-cart out of a lawnmower engine is to making a car to race in the Indy 500. Seriously. The ISPs are awful, the payload fractions are awful (because of the low ISP engines and high tank/structural masses), they don't deal with much TPS if any, etc. I.e., they don't deal with the real engineering problems of spaceflight, and thus aren't advancing anything. Cheer for those who are actually advancing technology.

          And no, before you state it, let me head it off: they're not helping parts be "mass produced" and thus cheaper. The materials that they use are generally all wrong (far more in common with aircraft) and the low performance engine designs share little to nothing in common with real rocket engines, which are more like jet engines. And of course, since they don't need much of any TPS, they don't advance TPS research/costs (most of which are labor, anyways)

      It's one of those ideas that seems straightforward... Until you do the actual math.

      It turns out that it only takes about 5% of the fuel (or less) to get to the altitude that a typical airship flies - and that a reasonable size payload requires an airship twice the size of the Hindenburg to carry it. Given that a) fuel costs are down in the noise and b) the (extremely fragile) airship costs hundreds to thousands of times more than is saved in the costs of tankage - it suddenly seems like a much less nifty idea.

      Anyhow, the main problem in getting to orbit isn't about altitude, it's about speed.

      • If the main problem is speed, then what the hell good is launching from an extremely slow (relative to orbital speed...) aircraft? Also why is it more expensive to launch into high orbits, those require less orbital speed, more altitude.

        But reducing fuel mass by 5% allows you to increase your payload mass by at least a factor of two for many launch vehicles. I'm not sure balloon-launch is the way to go, because as you say speed is the issue, but rockets are so enormously inefficient that relatively small percentage savings

The sole purpose of the ctv is to get people in low earth orbit from an in atmosphere launch using a pre-existing capsule design.

He had a rocket called Conestoga in the 80s that ran into the infamous "brother-in-law problem" at NASA. He was also the driving force behind another Mojave airport first: the Roton demonstrator. Now he's back with the world's most famous aircraft designer and a bunch of other people from the space activist community.

    Burt needs no introduction: he's da man. Burt builds the coolest planes in the world and has finally started building spaceships.

    So, t/space has been doing droptests, excellent! They have a great capsule demo and seem to be trying to stretch their funding as far as possible. I'm pretty sure they said that the "CXV" was proposed specifically outside the CEV RFP, because they refuse to fill out that much extra paperwork. You can see what Mr. Hudson was working on in the early 00's here: http://hmx.com/ [hmx.com] The pdf is his proposal for a capsule (manned/cargo) for the old Alternative Access to Station program, gives a good idea of where the CXV's heritage is.

    t/space is an amazing team. If they can keep the funding coming, they will deliver on this craft.

    • Do you work for t-space? Christ did I just read a press release?
      • No, just a huge fan. I've met Gary at a conference and followed his career. I was at the September SpaceShipOne launch, too. That was FREAKING AWESOME.

        I am what you might call a space advocate. Space freak? Space geek! I'm for space development and colonies and all that. I just think that companies like t/space, SpaceDev, SpaceX etc are going to get us there while NASA spins their wheels.

        Whore for the private spaceflight industry? Yes, please.

  • the tether held on to the package until after the motors had achieved sufficient thrust and then released it... that way, if the engines don't make it, they can be shut down and the very expensive package retrieved by means of a winch... if needs be, jettison the motor bit and just retrieve the payload.
  • Unfortunately, with the recent selection of Boeing/Northrop-Grumman and Lockheed-Martin as the two competing teams for the contract to build the Shuttle's successor, t/Space's future path is somewhat uncertain.

    I would think their path is clear: Get one of those other two to buy them!

    If the idea is that good, one or both of the contractors could license it from them. Could be very profitable for t/Space. Also likely: they get bought up by one of the big guys.
  • t/Space recently released a paper with more details of the air-launch method and the flight tests here:
