Multirotor is the umbrella term for the family of unmanned aircraft, which include the quadrotor, hexarotor and other vertical take-off and landing (VTOL) aircraft that employ multiple main rotors for lift and control. Development and testing of novel multirotor designs has been aided by the proliferation of 3D printing and inexpensive flight controllers and components. Different multirotor configurations exhibit specific strengths, while presenting unique challenges with regards to design and control. This article highlights the primary differences between three multirotor platforms: a quadrotor; a fully-actuated hexarotor; and an octorotor. Each platform is modelled and then controlled using non-linear dynamic inversion. The differences in dynamics, control and performance are then discussed.

“…Recently, Anderson & Thomson have developed a mathematical model for simulating the RPG/Rotorcraft engagement to evaluate the efficacy of various evasion strategies [11] using a bespoke multi-fidelity simulation engine [12]. Known as MAVERIC (Modeling of Autonomous Vehicles using Robust, Intelligent Computing), this simulation engine handles multiple dynamic agent models of differing fidelity and integrates them to provide an accurate, computationally efficient solution to a user-defined vignette.…”

It has long been acknowledged that military helicopters are vulnerable to groundlaunched threats, in particular the RPG-7 rocket-propelled grenade. Current helicopter threat mitigation strategies rely on a combination of operational tactics and selectivelyplaced armour plating which offer little protection. However in recent years a number of active protection systems (APS) designed to protect land-based vehicles from rocket and missile fire have been developed. These systems all use a sensor suite to detect, track and predict the threat trajectory, which is then employed in the computation of a defensive kill mechanism intercept trajectory. In this paper it is proposed that although a complete APS in its current form is unsuitable for helicopters, the APS track and threat trajectory prediction sub-system could be used in the computation of an optimal evasive manoeuvre. It is further proposed that this manoeuvre can be found by solving a specific pursuit-evasion differential game. To evaluate the game, nonlinear dynamic and spatial models for a helicopter, RPG-7 round and gunner & evasion strategies were developed and integrated into a bespoke simulation engine. Analysis of the results from representative vignettes demonstrates that the simulation yields the value of the engagement pursuit-evasion game. It is also shown that in the majority of cases survivability can be significantly improved by performing an appropriate evasive manoeuvre. Consequently this simulation may be used as an important tool for designing and evaluating evasive tactics and manoeuvres leading to improved rotorcraft survivability.
