The rocket effect mechanism in neutron stars in supernova remnants [PDF]
, 2023 While the dipole magnetic field axis of neutron stars is usually postulated to cross the star's centre, it may be displaced from this location, as it has been recently indicated in the millisecond pulsar J0030+0451. Under these conditions, the electromagnetic rocket effect may be activated, where the magnetic field exerts a net force, accelerating the ...

Simultaneous Sizing of a Rocket Family with Embedded Trajectory Optimization [PDF]
arXiv, 2023 A sizing procedure for a rocket family capable of fulfilling multiple missions considering the commonality is presented. The procedure aims to take full advantage of sharing a common part across multiple rockets whose payload capability differs entirely, ultimately leading to cost savings in designing a rocket family.

Experimental Study on the Mass Flow Rate of the Self-Pressurizing Propellants in the Rocket Injector
Aerospace, 2021 High vapor pressure propellants such as nitrous oxide are widely used in experimental hybrid and liquid rockets as they can be used in a self-pressurization mode, eliminating the need for external pressurization or pumps and simplifying the design of the
