The Zero Propellant Maneuver (ZPM) maneuvers the space station by large angle, utilizing the Control Momentum Gyroscopes (CMGs) only. A robust tracking guidance strategy is proposed to enhance its performance. It is distinguished from the traditional trajectory tracking guidance in that the reference trajectory is adjusted on-line, under the inspiration of eliminating the discrepancy on the tot...

A MW-class electrothermal arcjet based on a water-cooled, wall-stabilized, constricted arc discharge configuration was subjected to extensive performance testing using hydrogen and simulated ammonia propellants with the deliberate aim of advancing technology readiness level for potential space propulsion applications. The breadboard design incorporates alternating conductor/insulator wafers to ...

Abstract In order to solve the problem of long time consuming and low efficiency in solving complex combustion surface solid rocket propellant, a calculation method based on parameterized volume Boolean operation was proposed. After model propellant created by using 3D modeling software, burning used perform difference between obtained growth entity entity. Through Sensitivity Analysis function...

High-energy substances like effect propellant and are used in fireworks. In the process of manufacture, transportation, use, heat can easily get out control. The emulsifier polyisobutene succinimide (T152) is frequently to emulsify explosives. Given thermal safety fireworks, this paper T152 propellant. Thermogravimetric Fourier-transform infrared spectrometry differential scanning calorimetry w...

Abstract Polydopamine (PDA) has been widely used in the field of energetic materials; however, there are few reports on ammonium perchlorate (AP) coating PDA. In this article, to improve mechanical properties GAP‐ETPE‐based propellant, a two‐step method was coat AP with PDA and glycidyl azide polymer (GAP) based propellant. SEM, EDS, XRD, XPS were analyze morphology composition PDA@AP, while co...

Aiming for designing a novel catalyst for N(2)O as a green propellant, Ir-substituted hexaaluminate, which can initiate N(2)O decomposition at 623 K and can sustain the stability at 1473 K, has been developed for the first time.
