Martian Coaxial Tiltrotor Aerobot: Aerodynamic Shape Design of Coaxial Tiltrotor and Robust Flight Control.

, 2013
Mars has been an active planet for space exploration since the 1960s. The future Mars missions, such as searching for life, could be accomplished by the technique up to date, but the Martian aerobots allow a longer range and a lower altitude compared with rovers and orbiters, respectively.

Adaptive Neural Network Extended State Observer-Based Finite-Time Convergent Sliding Mode Control for a Quad Tiltrotor UAV

IEEE Transactions on Aerospace and Electronic Systems, 2023
The internal and external disturbance of the quad tiltrotor unmanned aerial vehicle (UAV) stem from its rotor tilting motion and wind disturbance, which affect the control stability of the quad tiltrotor UAV in full flight.

Noise considerations for tiltrotor

25th Joint Propulsion Conference, 1989
A projection is made of the technology-development requirements faced by aircraft designers contemplating the evolution of V-22-type tilt-rotor aircraft technology into a civilian tilt-rotor commuter aircraft of the requisite scale and payload. These research challenges are noted to often involve the reduction of noise level to values tolerated by ...
