This study presents an optimal design approach of a pintle injector for a deep throttlable
liquid-propellant rocket engine (LPRE). Even though the pintle injector is used in rocket …

This paper proposes an optimal staging method for reusable launch vehicles considering
velocity losses. The proposed method expands a traditional stage optimization approach for …

Removing the thrust termination mechanism of solid rocket motors is an inevitable trend but
reduces the ability of terminal multi-constraints. This paper presents an improved analytic …

This paper proposes a noniterative feedback midcourse guidance algorithm for intercepting
a ballistic target. The virtual impact point (VIP) concept, which is the intersection point …

This paper proposes integrated optimal guidance for the reentry and landing of a rocket
using the multi-phase pseudo-spectral convex optimization method. For a successful return …

This paper researches the ascent trajectory optimization problem in view of multiple
constraints that effect on the launch vehicle. First, a series of common constraints that effect …

To address the problem of depletion shutdown precise guidance for a long-range vehicle in
large deviation condition, an online guidance algorithm based on Bezier curves and zero …

The simultaneous interception of multiple exo-atmospheric threat targets can leave no buffer
time for the targets and greatly reduces targets' penetration probability. This paper proposes …

AN INSTANTANEOUS impact point (IIP) guidance law changes the current IIP of a rocket to
the desired location on the surface of the Earth. Traditionally, the IIP guidance law has been …
