General Electric has a Tumblr and they seem to be doing a fine job at it! Seen here:
A pulse-detonation actuator from our Energy & Propulsion lab. It produces high-pressure, pulsating supersonic jets, which help with airflow control in high-speed travel. Active airflow control reduces the drag, noise, and fuel consumption of an aircraft, making for smoother and more efficient flight.
