JNTUK B.Tech Helicopter Engineering gives you detail information of Helicopter Engineering R13 syllabus It will be help full to understand you complete curriculum of the year.
Course Objective
The main objective of the subject is to make the students to know about basic helicopter components, basic control mechanisms, helicopter aerodynamics and helicopter stability. It also helps in the estimation of ground effect on Hovercraft and ground vehicles. The students are imparted with the knowledge of performance of helicopter for various flight conditions. Also one unit of course is dedicated to VTOL/STOL aircrafts and GEM’s.
UNIT – I : ELEMENTS OF HELICOPTER AERODYNAMICS : Configurations based on torque reaction – Jet rotors and compound helicopters.
UNIT – II : ROTOR CONTROL : Methods of control – Collective and cyclic pitch changes – Lead-lag and flapping hinges. IDEAL ROTAR THEORY Hovering performances – Momentum and simple blade element theories.
UNIT – III : ROTOR PERFORMANCE : Figures of merit – Profile and induced power estimation – Constant chord and ideal twist rotors.
POWER ESTIMATES : Induced, Profile and Parasite power requirements in forward flight -Performances curves with effects of altitude.
UNIT – IV : STABILITY AND TRIM :Preliminary ideas on helicopter stability.
UNIT – V : LIFT AND CONTROL OF V/STOL AIRCRAFT : Various configurations – Propeller, Rotor ducted fan and jet lift – Tilt wing and vectored thrust – Performances of VTOL and STOL aircraft in hover, Transition and Forward motion.
UNIT – VI : GROUND EFFECT MACHINES : Types – Hover height, Lift augmentation and power calculations for plenum chamber and peripheral jet machines – Drag of hovercraft on land and water. Applications of hovercraft.
