INTRODUCTION:
While a helicopter is a far more complex machine than an aeroplane, the fundamental principles of flight are the same.
The rotor blades of a helicopter are identical to the wings of an aeroplane –when air is blown over them, lift is produced.
The crucial difference is that the flow of air is produced by rotating the wings – or rotor blades – rather than by moving the whole aircraft.
When the rotor blades start to spin, the air flowing over them produces lift, and this can cause the helicopter to rise into the air.
So, the engine is used to turn the blades, and the turning blades produce the required lift.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Normal Labour/ Stages of Labour/ Mechanism of LabourWasim Ak
Normal labor is also termed spontaneous labor, defined as the natural physiological process through which the fetus, placenta, and membranes are expelled from the uterus through the birth canal at term (37 to 42 weeks
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.

3. “Knowing how the components and systems work on the
helicopter enables the pilot to more easily recognize
malfunctions and possible emergency situations.
Understanding the relationship of these systems allows
the pilot to make an informed decision and take the
appropriate corrective action should a problem arise.”

4. Fuselage- outer core of the airframe. This is the
aircraft’s main body that houses the cabin. This also
houses the engine, transmission, avionics, flight
controls and the powerplant.

5. Main rotor system- the rotating part of the helicopter that
generates lift. It consists of a mast, hub and rotor
blades. The mast is a hollow shaft that extends
upward to the hub which the rotor blades are attached
to.
Helicopter Flying Handbook 2012
6. Swash plate assembly- “The purpose of the swash plate
is to convert stationary control inputs from the pilot
into rotating inputs which can be connected to the
rotor blades or control surfaces. It consists of two
main parts, stationary swash plate and rotating swash
plate. “

8. Freewheeling unit- this unit automatically disengages the
engine from the rotor system when the engine
revolutions per minute (rpm) are less than main rotor
rmp. Doing this, it allows the main rotor and the tail
rotor to continue to turn normally inflight speeds.

9. Antitorque system- a helicopter with a single, main rotor
system require a separate system. This is through a
variable pitch, antitorque rotor or tail rotor.

11. ENGINES
Reciprocating engine- also called piston engines, used in
smaller helicopters because they are simple and
inexpensive to operate
Turbine engine- more powerful and widely used in
helicopters, they produce more power but are more
expensive to operate
Helicopter Flying Handbook 2012
12. TRANSMISSION SYSTEM
“The transmission system transfers power from the
engine to the main rotor, tail rotor, and other accessories
during normal flight control. The main components of
the transmission system are the main rotor transmission,
tail rotor drive system, clutch, and freewheeling unit. The
freewheeling unit or autorotative clutch allows the main
rotor transmission to drive the tail rotor drive shaft during
autorotation.”
