FACTOID #53: If you thought Antarctica was inhospitable, think again - its land area is only ninety-eight percent ice. Reassuringly, the other 2% is categorised as "barren rock".
The A1 was the first rocket design in the Aggregate series, which lead to the V-2 (A4). It was designed in 1933 by Wernher von Braun in a German Army research program at Kummersdorf headed by Walter Dornberger. The rocket was 1.4 m long, and had a takeoff weight of 150 kg. The engine, designed by Arthur Rudolph, used alcohol and liquid oxygen, and produced 3 kilonewtons of thrust. The rocket was designed to be stabilized using a heavy rotating wheel in the nose, but there was concern that this might cause problems with the liquid fuels. Although the engine had been successfully test fired, the first flight attempt blew up on the launching pad. Since the design was thought to be unstable, no further attempts were made, and efforts moved to the A2 design.

The rocket was 1.4 m long, and had a takeoff weight of 150 kg.
The rocket was designed to be stabilized using a heavy rotating wheel in the nose, but there was concern that this might cause problems with the liquid fuels.
However, in contrast to the A1, the A2 had the stabilization gyroscopes in the center of the rocket between the alcohol and oxygen tanks, which made it more stable.
Nerf rockets usually have an elongated cylindrical fuselage that is made of a foam rubber material and that has fins affixed to and extending outwardly from the tail of the rocket.
In model rockets, the parachute usually is folded and stowed in the nose-cone section of the rocket during flight.
However, as the rocket slows near its apogee, the force of the wind is overcome by the biasing force of the rubber band 53, and the nose-cone 54, flap 47, and latch keeper 38 are hinged backward.
