What is the specific impulse of liquid hydrogen?

What is the specific impulse of liquid hydrogen?

Use of atomic hydrogen might yield a specific impulse of about 1,200 to 1,400 seconds.

Is hydrogen peroxide hypergolic?

Cold hydrogen peroxide and kerosene are not hypergolic, but concentrated hydrogen peroxide (referred to as high-test peroxide or HTP) run over a catalyst produces free oxygen and steam at over 700 °C (1,300 °F) which is hypergolic with kerosene.

What are the characteristics of hypergolic liquids?

Hypergolic fluids are toxic liquids that react spontaneously and violently when they contact each other. These fluids are used in many different rocket and aircraft systems for propulsion and hydraulic power including: orbiting satellites, manned spacecraft, military aircraft, and deep space probes.

How do you calculate specific impulse?

The specific impulse formula is Isp = F / (ṁ × g) , the unit of Isp = 1 N/((kg/s) × (m/s²)) = 1 N/(kg⋅m/s³) . But since 1 N = kg⋅m/s² , the units of specific impulse becomes (1 kg⋅m/s²) / (kg⋅m/s³) = s .

What is the formula to find specific impulse?

Specific impulse is inversely proportional to specific fuel consumption (SFC) by the relationship Isp = 1/(go·SFC) for SFC in kg/(N·s) and Isp = 3600/SFC for SFC in lb/(lbf·hr).

What is meant by hypergolic?

Definition of hypergolic 1 : igniting upon contact of components without external aid (such as a spark) 2 : of, relating to, or using hypergolic fuel.

How is specific impulse calculated?

How do you calculate ISP?

The unit of specific impulse is seconds . The specific impulse formula is Isp = F / (ṁ × g) , the unit of Isp = 1 N/((kg/s) × (m/s²)) = 1 N/(kg⋅m/s³) .

What is specific impulse KSP?

From Kerbal Space Program Wiki. The specific impulse (usually written as Isp, or in-game as ISP) defines the efficiency of an engine. It is thrust per the rate of fuel consumption. Or equivalently, it is change in momentum per amount of fuel consumed.

How can I find my ISP?

The unit of specific impulse is seconds . The specific impulse formula is Isp = F / (ṁ × g) , the unit of Isp = 1 N/((kg/s) × (m/s²)) = 1 N/(kg⋅m/s³) . But since 1 N = kg⋅m/s² , the units of specific impulse becomes (1 kg⋅m/s²) / (kg⋅m/s³) = s .

How do you solve ISP?

What is specific impulse measured in?

seconds
In the English units, m is the weight flow rate in pounds per second. Since the thrust is in pounds, this leaves the unit of specific impulse to be seconds. For a more physical definition, specific impulse must be thought of as pounds of force per pound per second of propellant flow.

What is the ISP of hydrazine?

Specific impulse sea level: 292 s. Location: 1780. Optimum Oxidizer to Fuel Ratio: 1.34.

What is specific impulse formula?

The specific impulse Isp is given by: Isp = Veq / g0. where g0 is the gravitational acceleration constant (32.2 ft/sec^2 in English units, 9.8 m/sec^2 in metric units). Now, if we substitute for the equivalent velocity in terms of the thrust: Isp = F / (mdot * g0)

What is bipropellant propulsion?

A bipropellant is a two component rocket propellant using liquid, hydrogen and liquid oxygen, transported into separate combustion chambers, the fuel and oxidizer. A bipropellant creates propulsion by using fuel and oxidizer to create thrust.
