Sandia conducts alternative pyroshock testing

A 100lb solid steel projectile, fired from Sandia National Laboratories’ 6in gas gun, impacts material on a resonant bar attached to a test article. The impact initiates a wave that travels through the resonant bar assembly into the test article, simulating a stage separation pyroshock event.

Do you see a strong industry demand for more flight test pilots and flight test engineers to work in the ever-growing civil aviation sector? And if so, are the skills required any different from those needed for the defense sector?

A rainbow view of NASA’s RS-25 engine test

NASA engineers announced recently that they had conducted their first RS-25 test of 2017 on the A-1 Test Stand at Stennis Space Center near Bay St Louis, Mississippi, on February 22, continuing to collect data on the performance of the rocket engine that will help power the new Space Launch System (SLS) rocket.

Shown from the viewpoint of an overhead drone, the test of development engine No.0528 ran the scheduled 380 seconds (six minutes and 20 seconds), allowing engineers to monitor various engine operating conditions. The test represents another step forward in development of the rocket that will launch humans aboard Orion deeper into space than ever before.

Four RS-25 engines, together with a pair of solid rocket boosters, will power the SLS at launch on its deep-space missions. The engines for the first four SLS flights are former space shuttle main engines, which were tested extensively at Stennis and are some of the most proven engines in the world.

Engineers are conducting an ongoing series of tests this year for SLS on both development and flight engines for future flights to ensure the engine, outfitted with a new controller, can perform at the higher level under a variety of conditions and situations. Stennis is also preparing its B-2 Test Stand to test the core stage for the first SLS flight with Orion, known as Exploration Mission-1. That testing will involve installing the flight stage on the stand and firing its four RS-25 engines simultaneously, just as during an actual launch.
