Estes C11-3 Engine

Estes C11 3 Engine

Estes model rockets are Americas leading brand. C11′s have a higher intermediate and peak thrust than regular C’s. This allows C11′s to launch heavier model rockets. All Estes model rocket engines have a letter-number-number code. (e.g., C11-3) C = TOTAL IMPULSE – This letter is the total power (in Newton-seconds) invented by the engine. Each succeeding letter has up to twice the total power as the former letter. (Example: “B” engines have up to twice the power of “A” engines, which results in approximately twice the altitude the rocket will reach.). 11 = AVERAGE THRUST – This number shows the engine’s intermediate push or how fast the engine powers the rocket to go. The higher the number, the rapidly and without delay the speed. It is measured in Newtons (4.45 Newtons = 1 lb.). 3 = TIME DELAY – This number gives you the time delay in seconds among the of the thrust phase and ignition the ejection charge.
