Hohmann transfer orbit

Examples of Hohmann transfer orbit in the following topics:

• Orbital Maneuvers

  • The rest of the flight, especially in a transfer orbit, is called coasting.
  • The Hohmann transfer orbit is an elliptical orbit used to transfer between two circular orbits of different altitudes in the same plane.
  • The orbital maneuver to perform the Hohmann transfer uses two engine impulses that move aspacecraft onto and off the transfer orbit, as diagramed in .
  • Hohmann transfer orbits are the most efficient with fuel.
  • Other non-Hohmann types of transfer orbits that are less efficient with fuel exist, but these may be more efficient with other resources (such as time).

• Satellites

  • Low Earth orbit is any orbit below 2000 km, and Medium Earth orbit is any orbit higher than that but still below the altitude for geosynchronous orbit at 35,786 km.
  • High Earth orbit is any orbit higher than the altitude for geosynchronous orbit.
  • Hohmann transfer orbit: An orbital maneuver that moves a spacecraft from one circular orbit to another using two engine impulses.
  • Geosynchronous transfer orbit: An elliptic orbit where the perigee is at the altitude of a Low Earth orbit (LEO) and the apogee at the altitude of a geosynchronous orbit.
  • Geostationary transfer orbit: An elliptic orbit where the perigee is at the altitude of a Low Earth orbit (LEO) and the apogee at the altitude of a geostationary orbit.

• Rotational Kinetic Energy: Work, Energy, and Power

  • Due to conservation of angular momentum this process transfers angular momentum to the Moon's orbital motion, increasing its distance from Earth and its orbital period.

• Charge Separation

  • ., they can be transferred from atom to atom) it is possible for the phenomenon of "charge separation" (often referred to as static electricity) to occur.
  • In chemistry, this charge separation is illustrated simply by the transfer of an electron from one atom to another as an ionic bond is formed.
  • This is because electrons from one have transferred to the other, causing one to be positive and the other to be negative.
  • For example, a nearby negative charge can "push" electrons away from the nucleus around which they typically orbit.

• Electric Charge in the Atom

  • More important is the fact that electrons are labile; that is, they can be transferred from one atom to the next.
  • It is through electronic transfer that atoms become charged.
  • However, because electrons can be transferred from one atom to another, it is possible for atoms to become charged.
  • Small electrons orbit the large and relatively fixed nucleus of protons and neutrons.

• Modelling the Stress

  • The disk gets thinner as the value of $\alpha$ increases and gets fatter as the infall velocity approaches the orbital velocity.
  • We can combine the $\alpha$-prescription with vertical radiative transfer to obtain an estimate of the central density and temperature of the disk.
  • By combining the previous equation with with vertical radiative transfer, we obtain

• Water Waves

  • As long as the waves propagate slower than the wind speed just above the waves, there is an energy transfer from the wind to the waves.
  • As the wave amplitude (height) increases, the particle paths no longer form closed orbits; rather, after the passage of each crest, particles are displaced slightly from their previous positions, a phenomenon known as Stokes drift.
