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

Established that, directivity diagram of the system of “basic antenna – fuselage of helicopter” becomes a function of the time due to the presence of the metal main screw, which during rotation, periodically changes geometry of aircraft body. In this case... 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

Based on the mathematical modeling systems such "standard antenna–helicopter fuselage" effects pulsation its directional diagram. Indicated causes pulsation and their features. Indicated effects, which may be result of pulsation directional diagram

Aerodynamic characteristics of helicopter engine side air intakes are investigated. The experimental data set is obtained by wind tunnel testing of a full-scale helicopter fuselage section model. For the simulation of realistic engine operation, engine ma... see more

Boundary Element Method (BEM) is a widely used technique for the aerodynamic analysis of lifting bodies, due to the good compromise between fidelity and computational costs. This is especially true in rotorcraft applications, where the effects of the roto... see more

PT. Famindo Inovasi Teknologi (PT. FIT) is a company that works in the drone industry, and currently PT. FIT receives a request from Badan Keamanan Laut Republik Indonesia (BAKAMLA) to design a drone that can float on water. Therefore, my purpose is to de... see more

This paper describes the experiment for learning and investigation of the helicopter laboratory model static and dynamic characteristics. Helicopter model is not the free flying one, as it has the two degrees of freedom â?? up / down movement and rotation... see more

Tujuan penelitian untuk memperoleh gambaran tentang hubungan antara kondisi sosial ekonomi keluarga dengan helicopter parenting. Kondisi sosial ekonomi pada artikel ini antara lain: pendidikan, pekerjaan, dan pendapatan. Metode penelitian menggunakan meto... see more
