Servo regulator, Throatless engines, Hold down test

Aug 4, 2005 notes

Despite not having time to do an update for a while, we have been steadily working...

Servo regulator

When we last worked with it, the setup showed what seemed to be a valve lash problem - flow would begin when the high pressure ball valve reached 15% open, but it wouldn't shut off until it was closed all the way back to 5%. Since we had fabricated our own actuator to valve adapter, we thought we might have allowed too much lash into the coupling. We built a new mount using helical beam couplers with zero lash, but that turned out not to help. The coupling seems tighter, with the valve following every little jitter of the actuator, but the flow behavior seems to be an aspect of the seals in the ball valve, not the linkage between the actuator and the valve.

This cracking problem is only really an issue at very low flow rates, so we were able to do some flow tests at roughly the performance levels that our single-man space shot vehicle will use. With a single large nitrogen bottle feeding the servo regulator, we did the following test:

2700 psi initial bottle pressure

60 gallons of water at 230 psi and 215 gpm flow rate

1800 psi final bottle pressure

2" plumbing, 1" valve

The small fittings at the bottle valve became the limiting factor as the pressure dropped below about 2200 psi, with the servo valve eventually going wide open and still not quite being able to keep up. Our flight vehicle pressurant tanks will manifold directly out of bottle necks with a -10 fitting, so they won't become flow limited at all. When our new 36" hemispheres arrive, we will be welding up the full tankage and pressurization system for the big vehicle and doing water flow tests in preparation for testing a 5,000 lbf class engine.

Speaking of spheres, here are a couple pictures of the tear area on the burst one:

Throatless engine

I was recently looking at the table in Sutton regarding losses due to small chamber to throat contraction ratios, and they weren't as significant as I had remembered them. A chamber with no contraction ratio at all will lose 20% of its thrust due to pressure losses from accelerating gasses in the straight section, but the Isp loss is only 1.5%. The text mentions "throatless rockets" being used in some missile applications to minimize chamber length and dry mass at the expense of Isp. The text doesn't say if these were liquids or solids, but I assume they were solids.

However, this does open up the question of building liquid engines like that. If L* remained constant, you would have an extremely long engine that would probably be impossible to cool, but I could imagine the accelerating, high speed flow could reduce required combustion stay times significantly. A 1.5% Isp loss is utterly meaningless for our purposes, so a configuration that traded that for fabrication benefits could be quite useful.

We fired a few crude throatless lox / ethanol chambers, and the results were surprisingly encouraging. With a very crude injector (a spray nozzle for the lox and four straight horizontal jets for the ethanol), we measured a 190 Isp from a 12" long straight pipe combustion chamber. It melted in a couple seconds, but this was still very impressive. With a 3:1 expansion cone added, performance should increase about 15% to around 220 Isp. That would be right at theoretical va

Over the past decade, the personal computer industry has seen a major reduction in competition in the operating system platform market. A computer operating system platform is the software which computer users learn to operate their computer with, the software that independent software vendors develop applications for and the software that third-party computer hardware developers create compliant hardware for.

Competition in the desktop computer operating system space is practically non-existent, with one platform from a single supplier commanding a very high proportion (over 95%) of the Australian market. This single platform from a sole vendor is Microsoft Windows. Cybersource believes that a sizeable portion of this market share is due to the fact that over many years, most consumers were never given the option to acquire alternative operating system platforms. Instead, Microsoft Windows was always bundled with most vendors' computer products, whether consumers wanted that bundled product on not.

We have seen that the Australian Competition & Consumer Commission (ACCC) has acted in the best interests of consumers to increase competition in such areas as telecommunications. Cybersource wants to see similar actions introduced in the computer operating system platform space.

In the software market, as in the telecommunications market, a single, powerful and well-leveraged vendor can cause the reduction of real competition and the corralling of almost all consumers into a single monopolistic platform situation. This causes significant reduction in choice, price competitiveness and innovation. Cybersource calls upon the ACCC to rectify this situation for the benefit of the local Information Technology industry and of all Australian IT consumers.

Key Points

1. It is impossible or extremely difficult for consumers to purchase a desktop PC or laptop from a tier-1 or tier-2 computer manufacturer without also having to purchase an OEM copy of Microsoft Windows operating system platform.

2. Cybersource believes that this greatly reduces choice for consumers and competition for the industry. Such a reduction in choice, and consequent reduction in competition, costs the Australian economy hundreds of millions of dollars annually, through paying one vendor needlessly high prices for monopolistic products.

3. The computer market is many ways similar to the telecommunications market. When one vendor has over 95% of the market, that vendor should be bound by a universal service obligation to ensure that all consumers can access the content, documents and data which reside on that vendor's platform. Neglecting such an obligation hinders all consumers and third-party developers not using that vendor's platform, further increasing anti-competitive pressures.

4. Cybersource believes that such anti-competitive practices should be stopped as soon as possible, through remedies introduced by the ACCC, to secure both a broader competitive base and increased options for consumers.

5. The first remedy that Cybersource seeks from the ACCC is that all tier-1 and tier-2 vendors should be required to offer their desktop and laptop products without an operating system pre-installed, that this choice be presented to consumers as broadly as the products themselves are, and that the price difference between the with and without operating system options should also be clearly and broadly presented at retail outlets, on vendor marketing literature and vendor websites.

6. The second remedy that Cybersource seeks from the ACCC is that Microsoft should be required to offer unfettered and unencumbered access to all major content, document, data and applications formats which could enable interchange and interoperability between users of its platform and users of other alternative platforms.

I like it. Besides being very non-abrasive, it would make it very easy to use color as a visual cue. If the components are generally black and white, it really stands out when something red pops up.
