Let’s compare RP-1, hydrogen, methane, solid rocket fuel and even hydrazine-based hypergolic fuels. Going over these will pretty much cover the vast majority of rockets and what fuels they use. Let’s start off with the dirtiest of rocket propulsion, and that is solid rocket boosters. You...
Unlike driving, which involves fuel costs, parking fees, and vehicle maintenance, cycling requires minimal expenses. Once you have a bike and necessary safety gear, your primary cost is your time and energy, making it a sustainable and affordable option for daily commutes or leisurely rides. Ho...
If you burn a pound of rocket fuel, a pound of exhaust comes out the nozzle in the form of a high-temperature, high-velocity gas. The form changes, but the mass does not. The burning process accelerates the mass. Let's learn more about thrust next. Thrust The "strength" of a ...
These 10-pound (4.5-kg) darts are 2 feet (61 cm) long, approximately 1 inch (2.5 cm) in diameter and leave the barrel of the tank's cannon traveling at over 1 mile (1.6 km) per second. The dart has so much kinetic energy and is so strong that it is able to pierce the ...
Feed system: When the spacecraft needs more power, the antimatter will be released to collide with a target of matter, which releases energy. Magnetic rocket nozzle thruster: Like a particle collider on Earth, a long, magnetic nozzle will move the energy created by the matter-antimatter through...
Fuel cell stacksA single fuel cell produces only about as much electricity as a single dry-cell battery—nowhere near enough to power a laptop computer, let alone a car. That's why fuel cells designed for vehicles use stacks of fuel cells linked together in a series. The total electricity...
There is also a CodeProject article describing the basics of the implementation in a long-form tutorial. [Should I move it here? I think it's too much for a SO answer]. There is a full-featured library "Better Enums" that implements the macro in a single header file. It also impleme...
Even though the action and reaction of the rocket motor during burn is equal, the mass of the fire, gas, and smoke being propelled by the rocket engine is much smaller or less than the overall mass of the rocket being sent in the opposite direction. As a result, even though the force...
Why Doesn't the cooling system on a rocket engine burn the fuel? Writing in first person for fiction novel, how to portray her inner dialogue and drag it out to make a chapter long enough? How uncommon/problematic is a passport whose validity period (period between issue and expiry) is...
You don't need any special equipment like telescopes or binoculars as the secret is to take in as much sky as possible and allow at least 30 minutes for your eyes to adjust to the dark. Avoid using your phone and make sure you have the red light setting on flashlights to preserve ...
