|Airplane builders hard at work.|
|Comparing design variations.|
Blackbirds were used for their advanced photographic and electronic sensor systems, which collected intelligence for the Air Force and other federal agencies from the late 1960s through the 1980s.
The following information is extracted from a NASA factsheet about the SR-71:
|Still hard at work!|
The airframes were built almost entirely of titanium and other exotic alloys to withstand heat generated by sustained high-speed flight. Capable of cruising at Mach 3 continuously for more than one hour at a time, the Blackbirds provided a unique research platform for thermal experiments because heat-soak temperatures exceeded 600 °F.

Aerodynamic control surfaces consisted of all-moving vertical tail fins above each engine nacelle and elevons on the outer wings and trailing edges between the engine exhaust nozzles.

Class #2 – Tuesday 11 November – 7 PM at Squadron 188
Build and Launch:
1. AlkaFuji rocket - aka "Fizzy Flyer"
This activity illustrates Newton's Laws of Motion.
2. Build -"The Goddard Rocket"
We will introduce Dr Robert Goddard, the man who pioneered liquid propelled, controlled rocket flight, and build a flying model of his 1931 rocket.
Take home two rockets, then re-launch with your family and friends demonstrating Newton's Laws.
