Japan's space agency tests future supersonic scramjet engine specimen

NHK -- Jul 24
Japan's space agency has announced that it successfully test-launched a small research rocket, which conducted tests for a future supersonic scramjet engine.

The Japan Aerospace Exploration Agency, or JAXA, is researching the engine. The engine uses atmospheric oxygen to burn engine fuel with the airflow through it remaining supersonic or faster. As it does not need loaded oxygen on board, the scramjet will allow a heavier payload to be carried.

JAXA launched an S-520-RD rocket into space at 5:00 a.m. Sunday from Uchinoura Space Center in Kagoshima Prefecture in southwestern Japan.

The rocket reached an altitude of 168 kilometers three and half minutes after the launch. The nose of the rocket contains test equipment for the scramjet engine which was detached from the craft. ...continue reading
