We present a novel concept for a small mission to the four inner large satellites of Saturn. Leveraging the high efficiency of electric propulsion, the concept enables orbit insertion around each of the moons, for arbitrarily long close observation periods. The mission starts with a EVVES interplanetary segment, where a combination of multiple grav...
This study proposes a new automated strategy for designing and optimizing three-dimensional interplanetary low-thrust (LT) trajectories. The method formulates the design as a hybrid optimal control problem and solves it using a two-step approach. In Step 1, a three-dimensional model based on generalized logarithmic spirals is used with heuristics i...
The giant planets have a special place in our quest for learning about the origins of our planetary system and the search for life. On its mission to Saturn, Cassini discovered water plumes containing complex organic molecules emanating from the sixth largest moon of Saturn, Enceladus. This discovery suggests that Enceladus and other inner large mo...
Turbine as a key power unit is vital to the novel supercritical carbon dioxide cycle (sCO2-BC). At the same time, the turbine design and optimization process for the sCO2-BC is complicated, and its relevant investigations are still absent in the literature due to the behavior of supercritical fluid in the vicinity of the critical point. In this reg...
All our knowledge about Saturn and its icy ring system comes from the data obtained during the flybys of Pioneer 11, Voyager 1, Voyager 2 and Cassini, as well as from the observations carried out by Hubble Space Telescope. The discovery of water vapor plumes at the poles of Enceladus and other compelling evidence of the existence of subsurface wate...
Fast and precise propagation of satellite orbits is required for mission design, orbit determination and payload data analysis. We present a method to improve the computational performance of numerical propagators and simultaneously maintain the accuracy level required by any particular application. This is achieved by determining the positional ac...

Our knowledge about Uranus and its moons is scarce. To gain insight into the features of this planet and its satellites, an exploration mission is needed. Uranus axial tilt of 98⁰ requires a prohibitive amount of propellant for insertion into an equatorial orbit. To minimize the cost of the orbit insertion maneuver, a combination of low thrust (LT)...
The fossil fuels have been the most practical way to produce energy for industries, vehicles and homes due to their lower prices, good combustion properties and their availability compared to other types of fuels. However, in this era of modernization, one of the biggest challenges of humanity is depletion of fossil fuels may result the increasing...
Aerospace structures are typically semi-monocoque structures that are made up of thin-walled closed section reinforced with stiffeners. Stress analysis of such closed thin-walled structures which are statically indeterminate is tedious and time consuming. An educational software which can aid students in carrying out stress analysis of such idealiz...
Unmanned Aerial Vehicle (UAV) is becoming increasingly popular because it can perform variety of functions. These functions include surveillance, reconnaissance, monitoring, data collection and rescue operation. The purpose of this work is to design, fabricate and fly a low weight, low cost, small size UAV for a surveillance mission. The design is...
