Turbine as a key power unit is vital to the novel supercritical carbon dioxide cycle (sCO2-BC). At same time, turbine design and optimization process for sCO2-BC complicated, its relevant investigations are still absent in literature due behavior of fluid vicinity critical point. In this regard, current study entails multifaceted approach designing optimizing radial system an 8 MW sCO2 cycle. Initially, base calculated utilizing in-house analysis code (RTDC), where sharp variations...
Fast and precise propagation of satellite orbits is required for mission design, orbit determination payload data analysis. We present a method to improve the computational performance numerical propagators simultaneously maintain accuracy level by any particular application. This achieved determining positional needed corresponding acceptable error in acceleration on basis requirements, removing those perturbation forces whose effect negligible compared requirement, implementing an...
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 this work to design, fabricate fly a low weight, cost, small size UAV for surveillance mission. design carried out based on Advanced Aircraft Analysis (AAA) software. process starts with the specifications typical wing loading power were estimated in performance sizing...
We present a novel concept for small mission to the four inner large satellites of Saturn. Leveraging high efficiency electric propulsion, enables orbit insertion around each moons, arbitrarily long close observation periods. The starts with EVVES interplanetary segment, where combination multiple gravity assist and deep space low thrust reduced relative arrival velocity at As result, an unpowered capture via sequence resonant flybys Titan is possible. transfers between moons use low-thrust...
Abstract The fossil fuels have been the most practical way to produce energy for industries, vehicles and homes due their lower prices, good combustion properties availability compared other types of fuels. However, in this era modernization, one biggest challenges humanity is depletion may result increasing price. Studies found out that it possible improve physical chemical characteristics alternative fuel based biodiesel by using transesterification process hence act as an mineral diesel....
Abstract This study proposes a new automated strategy for designing and optimizing three-dimensional interplanetary low-thrust (LT) trajectories. The method formulates the design as hybrid optimal control problem solves it using two-step approach. In Step 1, model based on generalized logarithmic spirals is used with heuristics in combination gradient-based solver to perform an multi-objective global search of trajectories optimize parameters defining spirals, launch date, well number,...

Aerospace structures are typically semi-monocoque that made up of thin-walled closed section reinforced with stiffeners. Stress analysis such which statically indeterminate is tedious and time consuming. An educational software can aid students in carrying out stress idealized sections has been developed. The enables to select different types wing torsion box stiffeners, may be subjected bending, shear or torsional loads evaluate the resulting stresses on it. allows student idealize a...
