X-38 successfully completed the program's highest and longest drop test to date. Carried to a height of nearly 12000 meters by a B-52, the prototype flew over 11mins after deploying a new improved parafoil. This model also included automatic flight control software for the first time.

For more info, see the NASA PR: [--Link Dead--]X-38 INTERCEPTS ROAD HOME FROM ORBIT IN SUCCESSFUL FLIGHT TEST

[CNN.com - Space - Smooth sailing, rough landing for 'space lifeboat' - March 30, 2000 * SpaceViews Article: X-38 Completes Longest Drop Test Yet - Mar.30.00 ]

Check out HASTOL , a combination reusable hypersonic sub-orbital vehicle and orbiting tether system that's under study by a collaboration of Robert Forward's Tether Unlimited , Boeing and Univ. of Maryland. The tether swings down and grabs payloads from the vehicle and lifts them to orbit. The [--Error--]study so far has proven the general feasibility of the concept and is now trying to optimize the design.

News briefs... The VentureStar site posts a [--Error [--Time Out--]--]press release on the recent long duration test. It says that the firing also included the first demonstration of full power thrust vector control.

March 27, 2000

X-33 engine test succeeds on March 22 in a reaching the full 220sec duration that would be required for its missions. Acccording to the item on the Space History site, an even longer test of 250secs will be carried out on April 3 as well.

Ground effect first stage booster for an RLV has been proposed by a Russian group. New Scientist reports that a spaceplane would mount "on the back of a 1500-tonne, rocket-propelled seaplane, known in Russia as an 'ekranoplan' ". To top off this rather eccentric proposal, the spaceplane would land on the back, avoiding the need for landing gear. [Ed. The Soviet Union developed several ground effect prototypes, including a large multi-engine vehicle, but never succeeded in finding a suitable application for them. I guess the Russian inheritors of this technology are hoping space launching could be a winner for it.]

X-33 engine test interrupted 75secs into a planned full-duration 220secs run. No significant damage found. A fuel pump was detected to be out of normal range and so the control computers stopped the test. Corrections should be easily made to allow for tests to resume next week. See NASA Press Release .

Beal Aerospace's BA-2- a partially reusable booster. Beal recently tested the largest rocket engine developed [--Link Dead--]since Apollo 's F-1. ([--Link Dead--]Beal Aerospace Fires Largest Liquid Rocket Engine in 30 Years - Beal Press Release - March 4, 2000.)

The company is funded by banker Andrew Beal who has put together a top rate team that is pursuing new approaches to reducing the cost of launching heavy payloads. The BA-810 engine uses hydrogen peroxide/kerosene, for example, which avoids the cost and complexity of low temperature liquid oxygen and liquid hydrogen.

Using helium pressure-fed engines also avoids the weight and reliability problems of high speed pumps. The tanks and structure will make extensive use of light-weight composites filament-wound materials.

The first launch of the the 3-stage [--Link Dead--]BA-1 is planned for mid-2002. The BA-1 appears at first glance to be of a typical expendable design but according to the web site it will use "reusable technologies" for "primary stage recoveries at sea." Beal has also indicated that follow-on vehicles will be fully reusable.

Note also that many proposed designs of low cost RLVs have involved hydrogen peroxide. Validation of this approach could have a big positive spin-off effect on other projects.

Space News - Feb.28 - reported that Lockheed Martin has promised that it will absorb the extra cost for the aluminum hydrogen tank replacements for the failed composite tanks if NASA will send them the remaining $113 million in the program funding....

The smaller of the two payloads returned with the IRDT inflatable re-entry system was successfully protected from the intense heat. However, there was some impact damage due to the failure of a second-stage full deployment that was to act as a drag chute. The other entry payload, the Fregat upper stage, has not yet been found due to the severe weather at the time of the landing that probably left it buried in snow. The search is apparently postponed till Spring after the snow melts.

Ed. Note that successful development of such a lightweight inflatable reentry system could be a big plus for RLV development as well. Several of the proposed systems, such as Kelly's Eclipse and Pioneer's RocketPlane , involve only reusable first stages. They plan to use expendable upper-stages to deliver payloads to orbit. With an IRDT type system, the whole system would become reusable.

X-34 first powered flight is postponed to the fall according to the Aviation Week Jan. 31, 2000 issue. More static firing tests of the Fastrac engine were deemed necessary to reduce risks with an untried engine. The current plans go something like this:

  • Early Spring - high speed tow tests with the A-1 vehicle. The A-1 was originally intended only for captive carry tests but has now been upgraded to include all flight systems and structures as the A-2 & A-3 except for a dummy engine. It will serve as a backup if there are accidents with the other two vehicles.
  • Late Spring - unpowered drop tests of the A-1 from an L-1011 at 35,000ft.
  • Late Fall - A-2 will begin a series of 8 powered flights at Dryden Center at Edwards AFB. Speed will be increased from Mach 2.2 up to Mach 5 by the last flight.
  • 2001 - the A-2 will be moved to Kennedy Space Center where over the course of seven tests it will seek to prove turnaround capabilites as short as 24 hours between flights.
  • 2001-2002 - the A-3 will attempt to reach Mach 8 and 250k ft altitude during tests at Dryden.

News briefs..Aviation Week also reports that X-38 program successfully tested the largest parafoil ever. This parafoil spans 7500sq-ft and is a full-scale man-rated design [Large Parafoil test - NASA Space News Roundup - Feb.00 ] ....

There was also further information on the Hyper-X program's study of whether to recover the vehicles in the second and third flights by flying over Alaska and landing on the polar ice caps.

The first flight should occur this summer over the Pacific. This vehicle will be dropped from a B-52. After a kick by a Pegasus booster to reach Mach 7 at 95,000ft, the scramjet will fire for 7 seconds. It will then be lost at sea.

The second and third flights would occur in late 2000 and 2001 with the latter flight reaching Mach 10.

January 28, 2000

X-33 progress. The X-33 Timeline reports some good news for the project:

  • Jan 21 - an aerospike engine successfully ran a 60sec test. The test included vectoring, varied thrust levels, and varied hydrogen and oxygen mixture ratios. Next test will be for 120secs.

  • Jan 20 - aluminum hydrogen tank fabrication has officially been approved to replace the damaged composite tanks.
    - communications established for first time among the control and health monitoring computers and power systems.
    - thermal tile installation is proceeding on schedule.

  • Jan 19 - a review team started a 3 day technical examination of the X-33 and VentureStar programs.

January 27, 2000

Buzz Aldrin's StarBooster web site is now online. The proposed reusable first stage booster employs two jet engines to fly back to the launch site. The booster can be combined in[--Error--] different configurations with expendable upper stages to launch a variety of payloads to LEO and GEO. Two StarBoosters can be flow together to lift large payloads.

Flyback boosters, vertically launched first stages with wings attached to return to the launch site, are getting increasing attention these days. They are seen by some as a more realistic intermediate step to reducing launch costs rather than going directly to more dramatic technology like the SSTO VentureStar.

Besides the StarBooster, here are some other proposed flyback systems:

January 12, 2000

X-33 may switch to aluminum hydrogen tanks. After the failure of the composite tanks during tests last fall there has been speculation that the project might switch to aluminum tanks. The VentureStar, for which the X-33 is supposed to develop technology for, is already being designed with such tanks anyway. A Space.com article - Lockheed May Give Up On Composite Tanks in X-33 - Jan.7.00 - indicates that this approach is in fact being seriously considered. Lockheed-Martin's [--Link Dead--]Michoud center developed the new lightweight shuttle external tanks that use an advanced aluminum-lithium alloy and is apparently looking at building the X-33 tank.

Other developments include further development of the design of the Venturestar, whose payload now rides as a piggyback module. Lockheed Unveils Images of Revised Venturestar - Space.com - Jan.5.00

X-33 aerospike engine completes first full power test. The 18sec test on Dec. 18 resulted in some minor erosion well within tolerance levels. Further tests will continue in January. See [--Time Out--]Press Release .

Second X-34 vehicle construction advances. The wing section was attached to the fuselage of the A-2 in late Dec. The A-1 vehicle completed carry tests on a L-1011 last September. It will undergo unpowered drop tests this Spring. Then A-2 will carry out the first powered flights. A third vehicle is also in an early construction stage. See the article at SpaceViews .
