The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...
A model rocket is a small rocket designed to reach low altitudes (e.g., 100–500 m (330–1,640 ft) for a 30 g (1.1 oz) model) and be recovered by a variety of means. According to the United States National Association of Rocketry (NAR) 's Safety Code, [ 1 ] model rockets are constructed out of lightweight and non metallic parts.
The Q1 was the final development of the British 0-6-0 main line steam locomotive. Later designs of medium-powered freight locomotives, such as the LMS Ivatt Class 2 2-6-0 and LMS Ivatt Class 4 Moguls, had a 2-6-0 wheel arrangement: the 0-6-0 wheel arrangement was not used in the BR Standard designs of locomotive.

Aerojet Rocketdyne proposed in 2014 to "lobby the government to fund an all-new, U.S.-sourced rocket propulsion system." In June 2014, Aerojet initially projected it would cost under US$25 million per pair of engines, not including the up to US$1 billion estimated development cost to be funded by the government.
The RD-0120 (Russian: Ракетный Двигатель-0120, romanized: Raketnyy Dvigatel-0120, lit. 'Rocket Engine 0120', GRAU index: 11D122) was the Energia core rocket engine, fueled by LH 2 /LOX, roughly equivalent to the Space Shuttle Main Engine (SSME).
RocketMotorTwo (RM2) [1] is a family of hybrid rocket engines developed for the Scaled Composites SpaceShipTwo suborbital spaceplane. The first-generation engine was developed by Sierra Nevada Corporation (SNC), [2] from the late 2000s to May 2014. It was first ignited in flight during a SpaceShipTwo test launch in April 2013.
The first quarter, also known as Q1, is during the months of January, February and March. To be precise, this calendar quarter is from Jan. 1 through March 31. This is when the fiscal year starts ...
In contrast to the camera rocket Astrocam, the Oracle allows the making of a complete film of a rocket flight. The Oracle is best flown with a D12 engine (see Estes number coding), but can be flown with C11 engines. Oracle model rocket at apogee. During launch, the camera films downward; showing the launch pad and engine exhaust during ascent.
