To fulfill the objective of a predictive tool for rotorcraft, comprehensive analysis (CA) needs to be capable of providing both accurate and time-efficient predictions of rotor air loads and structural loads. The more recent methodology based on comprehen... see more

The relative depth periodic pulsations irregular directivity diagram electromechanicalformation with pin antenna body helicopter at other identical conditions depends on the establishment ofstandard vibrator. Based on numerical modeling are created graph ... see more

It is known that in alive nature every kind of animals improved their appearance for ages. That is why cars and air vehicles try to get a shape, which approximately like animals. For a last time helicopters blades are modeled like bird wing. In this paper... see more

The aerodynamic design of rotor blades is challenging, and is crucial for the development of helicopter technology. Previous aerodynamic optimizations that focused only on limited design points find it difficult to balance flight performance across the en... see more

The cause-effect relations between the levels of pulsations of the antenna system, caused bymain rotor rotating of the helicopter, and the probability of the bit error occurring in the digital datatransmission channels were established. Graph-analytical m... see more

The relations allow quantify degree of redistribution average signal power between its spectralcomponents and satellites that arise at the combination frequencies during rotation the main rotor of thehelicopter. Recommendations for permissible levels of s... see more

The main rotor rotation leads to the emergence the parametric system “standard antenna – body a helicopter”, in which outer radio interference and signal acquire spectral distortions. The features of new components of the signal spectrum and noises are id... see more

This paper presents an investigation into the design of a flight control system, using a decoupled non-linear sliding mode control structure, designed using a linearised, 9th order representation of the dynamics of a PUMA helicopter in hover. The controll... see more

This work addresses the involuntary interaction between the pilot and the vehicle, with specific reference to helicopters along the vertical (or heave) axis. The problem is described and formulated mathematically. Means of analysis are discussed. Focus is... see more
