摘要

In mid-October the pine and oak trees surrounding NASA John C. Stennis Space Center's Test Stand El will reverberate to a new sound as space launch company Stratolaunch fires up the first full-scale pre-burner of its future PGA rocket engine.Developed up until now in relative secrecy, the 200,000-lb.-thrust liquid-oxygen/hydrogen-fueled engine will be the world's largest additively manufactured space propulsion system and forms a pivotal part of the company's goal to make access to space more convenient, affordable and routine. Designed to power the family of air-launched vehicles unveiled by the company in August, the emergence of the PGA marks a major gambit in Stratolaunch's bid to take a slice of the growing small- and medium-payload space-launch market.However, neither an indigenous rocket engine nor an associated launch-er family were part of the original plan when the giant Stratolaunch carrier aircraft was first unveiled in 2011. At that stage, and for several years after, Stratolaunch anticipated air-launching payloads on a variety of vehicles that it studied for development with SpaceX, Orbital ATK and Aerojet Rocketdyne.
