The revolution in the design philosophy of space systems has stimulated the growth of demand for replenishment, particularly in sustaining the continuous service of small satellite constellations. However, it is still unclear whether it is economically feasible to implement lifecycle replenishment and how it is affected by space system designs. To...
The large-angle pendulous motion of the parachute system, which increases the touchdown impact loading to the structure and saturates the control system, is very disadvantageous to the security of the system. To determine the root cause of the pendulum motion and provide improved design to mitigate the risk, there is an urgent need for stability an...
We propose the solution of optimal problems in aircraft noise and environmental emissions on arrival and landing at a major international airport. We present two distinct cases: 1.) arrival flight of a single airplane; 2.) flight planning for a fleet of four different airplanes. Mathematically, they lead to a constrained optimal control problem: ei...
In recent years, there has been a steady increase in the small satellite launch market. With the rapid development of novel launchers, for small satellite owners and operators, how to effectively and efficiently choose appropriate launch vehicles has become a major concern. Based on updated launch records, a reliable launch data source for multi-at...
A multi-objective optimization procedure to design parachute triggering algorithm, based on Monte Carlo analysis of flight uncertainties, has been developed in this paper. Most of Mars explorations missions utilize parachute for a safe descent through the lowest of the atmosphere. The parachute triggering algorithm is designed to accommodate the ra...
The variable wind field is one of the most important factors that affects the homing precision of parafoil system. K-means clustering method is used to analyze the measured wind field data of one month in a certain area, and two clustering centers are obtained according to the wind field in the morning and evening. Adopt three-segments homing metho...

A summary is given of the validation of an integrated aircraft
environmental simulation software, with focus on acoustic and engine
exhaust emissions. First, an experimental campaign was carried out to
gather noise data of several commercial aircraft on departure from
Manchester airport (ICAO code: EGCC). Field measurements were taken
with micropho...
The rapid development of emerging concepts and technologies, e.g., modularity, standardization, and fractionation, has resulted in the miniaturization of satellites and simplification of mission design, as well as a move towards more responsive and economical systems. However, the current customized and labor-intensive design philosophy is not natu...
A multi-objective trajectory optimisation has been developed to minimise multiple environmental impacts (noise and exhaust emissions) from commercial airplanes. Three different non-gradient algorithms are used. First, a parameterization method is established for airplane departure trajectories, with path constraints considered where necessary. Seco...
Due to the lack of matched dedicated small satellite launch vehicles, launch opportunities as a rideshare or piggyback using a highly reliable launch system has become increasingly important for small satellite developers. The objective of this paper is to provide an aggregated value method as a strategy for developers to evaluate launch opportunit...
A multi-objective trajectory optimization framework based on the genetic algorithm has been developed to minimize environmental impact (noise and exhaust emissions). First, a parameterization method is established for the departure phase, with constraints considered for the actual flight scenarios. Second, a lateral parameterization method based on...
This research systematically evaluates the impacts on the environment regarding aircraft noise and exhaust emissions, aiming at identifying the potential optimal aircraft flight trajectories with respect to different objectives. A trajectory optimisation method based on genetic algorithms is developed to cover a wider range of formations of optimis...
