Perch Landing Assisted by Thruster (PLAT): Concept and Trajectory Optimization
A concept of the perch landing assisted by thruster (PLAT) for a fixed wind aircraft is proposed in this paper. The proposed concept is applicable to relatively large unmanned aerial vehicles (UAV), hence can overcome the limitation of existing perch landing technologies. A planar rigid body motion of an aircraft with aerodynamic and thruster forces and moments is modeled. An optimal control pr...
متن کاملPerch Landing Assisted by Thruster (plat): Six D.o.f Trajectory Optimization
This paper handles a trajectory optimization of fixed wing aircraft perch landing assisted by thruster. The paper develops aircraft model and deals with six-degree-of-freedom motion for further understanding of dynamic phenomena of proposed landing method. The landing maneuver is described as an optimal control problem minimizing the fuel consumption with specified terminal landing conditions. ...
متن کاملMoon Landing Trajectory Optimization
Trajectory optimization is a crucial process during the planning phase of a spacecraft landing mission. Once a trajectory is determined, guidance algorithms are created to guide the vehicle along the given trajectory. Because fuel mass is a major driver of the total vehicle mass, and thus mission cost, the objective of most guidance algorithms is to minimize the required fuel consumption. Most ...
متن کاملCollision Avoidance for an Aircraft in Abort Landing: Trajectory Optimization and Guidance
For a host aircraft in the abort landing mode under emergency conditions, the best strategy for collision avoidance is to maximize wrt to the controls the timewise minimum distance between the host aircraft and an intruder aircraft. This leads to a maximin problem or Chebyshev problem of optimal control. At the maximin point of the encounter, the distance between the two aircraft has a minimum ...
متن کاملTrajectory Design Employing Convex Optimization for Landing on Irregularly Shaped Asteroids
Mission proposals that land spacecraft on asteroids are becoming increasingly popular. However, in order to have a successful mission the spacecraft must reliably and softly land at the intended landing site with pinpoint precision. The problem under investigation is how to design a propellant optimal powered descent trajectory that can be quickly computed onboard the spacecraft, without intera...
