HM 5.6 Hot Fire – Limited Success

With this test, we were expecting our first hot fire of HM 5.6, but we experienced a minor mechanical issue. The pneumatically actuated fire valve, which lets the nitrous flow into the combustion chamber, opened too slowly, preventing the motor from properly igniting. The valve will be inspected and repaired or possibly replaced with a pyro-actuated valve. Our goal is to have the hot fire completed by next weekend.
