What is negative torque system?
Definition. Negative Torque is said to occur when conditions are such that air loading on a propeller causes it to drive the engine to which it is attached vice the normal condition in which the engine drives the propeller.
What is NTS system?
The NTS drag protection system is designed to reduce the urgency with which the pilot is required to feather the propeller of the failed engine and allows him/her to concentrate on controlling the aircraft.
What is NTS in aviation?
Non-Technical Skills ( NTS ) means specific human competencies, including critical decision making, team communication, situational awareness and workload management, which may minimise human error in aviation.
What is SHP in aviation?
The power of a turboprop engine is measured in shaft horsepower ( shp ). Since turboprop engines are gas turbine engines, some jet thrust is produced by exhaust leaving the engine. This thrust is added to the shaft horsepower to determine the total engine power, or equivalent shaft horsepower.
What is negative torque in motor?
The negative driving torque is defined as torque applied to load in the reverse direction of the motor rotation. When the servomotor driver controls the motor to drive its load with negative driving torque, the effects of the negative driving torque may damage the servomotor driver.
What is feathering the propeller?
On a variable pitch propeller, the drag can be minimized by rotating the blades until they are edgewise to the flight direction. This is called feathering the propeller. At this angle, the propeller does not rotate or rotates slowly; thus, its drag on the airplane is greatly reduced.
Who is NTS com?
NTS owns and operates a large network of test, inspection and certification laboratories across North America and around the world. Whether you are looking for environmental or dynamics simulation testing, EMC testing or various other services, we operate first class facilities from coast to coast and beyond.
What is NTS exam in Pakistan?
National Testing Service – Pakistan ( NTS ) is an organization in Pakistan that administers academic performance evaluation tests. NTS offers two main types of tests, the National Aptitude Test (NAT) and the Graduate Assessment Test (GAT). NAT is aimed at students seeking admission to colleges and universities.
What means CRM in aviation?
Description. Crew Resource Management ( CRM ) is the effective use of all available resources for flight crew personnel to assure a safe and efficient operation, reducing error, avoiding stress and increasing efficiency.
Which is better turboprop or jet?
A turbine engine is extremely light and produces tremendous power-to-weight as opposed to a comparable piston engine. Conversely, jet engines are less efficient than a turboprop but often make up for it by being faster, hence spending less time in the air for the same destination.
Why can’t turboprop fly at high altitudes?
A bit of an over simplification, but turboprops don’t fly that high because their propellers aren’t as efficient in the thinner air as jets. So they’re stuck down in the thick air and the weather and turbulence and ice producing clouds. Turbofan engines are more efficient at higher altitudes.
What are the disadvantages of a turboprop engine?
- Slower cruising speed. Since turboprops have a slower maximum efficient cruising speed – up to an average of 300 knots indicated airspeed (KIAS) depending on the aircraft – expect your overall flight time to be longer than it would be with a jet.
- Lower cruising altitude.
- Shorter range.
