    Abstract: The use of radioisotope power systems (RPSs) for nuclear-enabled National Aeronautics and Space Administration (NASA) missions is made possible through a long-standing arrangement between the Department of Energy (DOE) and NASA. The requirements for the power system come from NASA, but DOE performs the procurement, fueling, testing, and delivery. A... Show More
  • Hypersonic Glider Autopilot Using Adaptive Higher Order Sliding Mode Control with Impulsive Actions

    DOI: 10.11648/j.ajae.20180502.12
    Abstract: Hypersonic glider designs often exhibit limited control authority and poor transversal stability. Furthermore, the methods used for aerodynamic performance estimation at high flight altitudes and hypersonic speeds are inevitably inaccurate and uncertain. Hypersonic Glider performance could be severely degraded by using traditional control and autop... Show More

    Abstract: This proposal for the future colonization of Mars starts from the purpose of creating an expandable and modular community made of elements as transparent as possible with large windows that allow the view of Martian landscape as to mitigate psychologically effects derived from long stay away from planet Earth. To realize this aim, it will be necess... Show More
  • Adapting SE (3) Nonlinear Geometric Method to Control Single-Tri Rotors with Integrator

    DOI: 10.11648/j.ajae.20180502.14
    Abstract: This paper presents a new method for controlling tri rotor-type unmanned aerial vehicles (UAV) adapted from the SE (3) nonlinear geometric method for quadrotor-type UAV. Like its predecessor, the control strategy for single tri rotors is realized in a hierarchical architecture, containing both attitude controller and position controller. As a basis... Show More
