2007 Activities

MASSLAs next rocket engine coming up for test in 2007 is the Adventure 5, running at projected 450kg of thrust, that’s (4420N).

Adventure 5 is a rocket engine powerful enough to take a MASSLA rocket in to the skies. Based on previous Adventure 4 engine, Adventure 5 is very likely to succeed in coming test.

Weighting in at proximately Adventure 4´s weight and producing three times the thrust, the Thrust/Weight ratio will be considerably improved making it useful for powering rockets.

A shorter test series of Adventure 4 engine will be conducted to acquire some more data for experimental purposes where more gauges and load cells will be added, directly after that

Adventure 5 tests will begin.

After thoroughly tests have been conducted of MASSLAs rocket engines, an application for launching a rocket in Sweden will be filed with the SSC at Esrange.

Talks with key persons at SSC has under the years, indicates that MASSLAs engines systems can fulfil certain requirements that is necessary to test fly a rocket.

One of those is for example the possibility to turn of the engine during flight. Of course lots of other safety issues must be resolved but MASSLA

is confident that together all safety requirements can be meet.

Winter 2006 Test

The newly produced regenerative rocket engine was tested in January 2006.

Designed to deliver 150kg of thrust at (5km) above sea-level, the engine was tested 6 times.

The longest burn of the engine is 15 seconds and total accumulated burns of 1 min 6sek.

The latest tests indicate thrust levels above 100kg of thrust at sea-level.

No erosion on the combustion chamber was detected after the test runs and no damage to the engine was detected at all.

Despite low Thrust/Weight ratio of approximately 10, Improvement can be done to at least double T/W.

A short analysis indicates longer burn times can be sustained for a much longer than 15 seconds.

This is a milestone for MASSLA in the development of a safe engine for commercial use.

Summer 2005 Test

This is a picture of the MASSLA regenerative engine, due to some erosion of a weld the engine eventually failed.

The engine was designed to deliver 60kg of thrust, which it did for almost 6 seconds.

Spring 2004

In the spring of 2004 MASSLA conducted several more tests.

As the picture shows a rocket engine test stand, With some notes to its component.

Despite a simple pressurized system it became a fairly complex system to overlook during test firings.

Autumn 2003

MASSLA conducted dozens of test on the second engine 2003

The engine a low thrust (5 to 10kg of thrust) un-cooled type.
