turbine engine air inlet?

Yeah, air inlet.

Did you know that there are six different types of systems on an aircraft turbine engine as well as reciprocating engine?

Induction
Exhaust
Fuel Metering
Starting and Ignition
Lubrication, and
Cooling

Fun fact. lol

Anyone have note in Turbo-shaft engine?

I do not understand this one. Read and read and read and find no references for it.

Droop Compensator
When the helicopter rotor system power requirements increase, the N2NR RPM tends to decrease.
The reverse is true when the rotor system power requirements are decreased.
It is desirable to vary the rotor system power requirements without having to change the N2NR RPM.
In order to prevent an N2NR RPM variation when a power change is made, a droop compensator is provided.

The Droop Compensator resets the power turbine governor spring during a power change to keep the N2NR RPM as it was before the power change.
This allows the operator to increase the power delivered to the rotor system as the collective pitch is increased, while the N2NR RPM is maintained.

yep. aircraft engine are by far more complicated than any other engine. they're design to be compact. meaning there are many parts cramped together.

study about aircraft engine a bit in my therodynamic subject since some ship do use gas turbine engine(a type of engine which is almost similar to aircraft engine just a bit different in design)<<--for aircraft is turbojet engine if i'm not mistaken.

all te system you've mention also located onboard ship. just that it is more bigger compared to aircraft but it is much more simpler than aircraft. why? becoz the part is big. easier to maintain compared to small parts. imagine the main engine for ship is about the half the length of 4-storey school block.


i've notice that actually, a qualified marine engineer and licensed aircraft maintenance engineer actlly doing the same job juz that we're servicing different vehicle. we also don't need degree to get enter. juz experience and competency. a degree grad cannot become LAME without license and they also cannot be marine engineer without Certificate of Competency.

our pay is also based on our competency and type rating.

fo aircraft u have type rating : boeing 727, airbus 380

for ship u'll have : steam, motor, Steam & motor, electric, gas turbine. bla3.

haha. we're the same. actlly. realise it long ago until now tell it. haha.

From what i understand, basically in a two spool configuration, there's:

N1 = gas producer speed/rpm
N2 = power turbine (free-turbine) speed/rpm

In nature, the N2 tends to decrease whenever N1 (power) is increased. And when N1 decreased, then N2 tends to increase.

So in this case (rotor system), the droop compensator is installed to maintain and stabilize the N2 rpm; as power is increased or decreased by the collective movement.

Droop compensation is achieved by a linkage attached to a bellcrank of the collective pitch control. The purpose of this linkage is to change the (power turbine) governor position mechanically to anticipate the required action as the collective is moved. If the movement was not anticipated as collective is raised, the N2 system would slow down, thus the term droop.




Yup, aircraft uses turbojet. Airliners uses turbofan as it is relatively the most quiet in operation and very fuel efficient.

I believe sea vessels (ships) employ the turboshaft type.

Yeah, I think vessel will use turboshalf.

Nope.Those sponsored student by MAS or FELDA will be working with MAS.For private student,u can go anywhere.But if your result and discipline is good,the school it self will recommend u to MAS.

About the droop compensator;

The operation or mechanism may vary from engine to engine (Allison 250 and PT6 i.e.)

But the main purpose or basic concept remains the same. That is to maintain N2 in the variation of N1.

Yeah, thanks man. Asked the instructor yesterday and he told us all about it. Just need to sit down and read read read and imagine imagine imagine and only get idea.

No problem mate. Just glad to be of a little help.

And yea, in rotorcraft system especially the flight theory, you need to do a lot of imagining and visualizing to understand it. Even when lots of explanations were already given. lol

Added on July 30, 2009, 8:07 pmTomorrow will go back to MAS and ASP (SOJT) on engines, because today finished the course.
Need to wake up early early in the morning and come back late lol

By the way, you work in helicopters?
Because after graduated, MAS did't take us, we will venture all over the place that we can, one of it is helicopters.

Why? MAS already has too many technicians? LWTR holders?

they got their own trainee and lwtr holder..correct me if im wrong.

Yes, i am totally aware of that. Let me rephrase my question.

Is there already too many of them trainees at MAS? Are they not even considering taking any people trained/graduated from other training organisations?

I donno MAS taking more trainees or not because inside got alot, JMR, Poly, MIAT, METC, etc.
They will take maybe because can earn money.

They take other or not than I do not know. Because TJT program just open last 2 months. If I not wrong is 3 TJT classes. Those who works with aircraft 2 to 3 years from APR or others who is good will be promoted to be Jr.Tech in MAS. And poly first 2 batch are fully taught by MAS instructors, so they fully absorb to MAS as Jr.Tech.

So I'm 4th batch and taught by poly lecturer and MAS instructors, so MAS will come to poly and audit this August whether blablabla... if pass than maybe we will consider to be absorb in also. Failed we will be going any where to find works. Hehe, that why I ask about helicopters. hehe.

By the way, today went back to MAS and my BGT ASP instructor is Mr.Muzzafar....

okay i did research ...but i still hav some question that no answer...

in the miat website ( is that uni KL right ? ) ,
there shows about 7 course for the MIAT ,


Pre-Russian University Engineering Program
Bachelor of Aircraft Engineering Technology (Hons.) Mechanical
Bachelor of Aviation Management (Hons.)
Diploma in Aircraft Maintenance Technology Manufacturing
Diploma in Aircraft Maintenance Technology Composite
Diploma in Aircraft Maintenance Technology Avionics
Diploma of Engineering Technology in Avionics Maintenance
Diploma of Engineering Technology in Aeroplane Maintenance
Diploma of Engineering Technology in Helicopter Maintenance

Is there only Avionics Aeroplan and Helicopter Main. can become a LAE ? what different between avionic and aeroplane maintenance ?

Those are only diplomas and degrees offered by MIAT same as other colleges/institutes/universities offering their own diplomas/degrees.

The most important thing you must understand is that, in order to become an LAE, one must obtain the license (LWTR) from DCA by passing the exams/tests that are mandatory for you to take in the road to licensing. That's how the term Licensed Aircraft Engineer (LAE) came to use.

So it doesn't matter which diploma you take in MIAT. Coz ultimately you still need a license to be a full-fledged LAE. If there is any differences, it would be that;

-Avionics diploma: you are expected to become an Avionics LAE
-Aeroplane diploma: you are expected to become an Aeroplane LAE
-Helicopter diploma: you are expected to become a Helicopter LAE

But in the end of the day, you still have choices on which direction you want to go. As i said it, if you're taking helicopter diploma, you are only expected to become a helicopter LAE but not obligated. I know this one MIAT student who is on his final year diploma course of helicopter maintenance but he's going for aeroplane license and well on his way. The only thing that's left for him to do is the 6 month on-job training (OJT) and completing the necessary and appropriate work schedule before applying to DCA to sit for the exam.

Another thing, the only difference between a diploma-holder LAE and a degree-holder LAE is the amount of salary that they receive. And then there are the type-ratings that would further differentiate between LAEs.

And to finally answer your question, avionics LAE will be responsible for the maintenance of the electronic systems on-board the aircraft mainly the ones in the flight deck (cockpit). While aeroplane LAEs (generally speaking) are mainly responsible for the aircraft structure (airframe) maintenance.

So, i'll say it again, irregardless of which diploma you take in MIAT, be it avionics, aeroplane, helicopter, composite, or manufacturing, you can still become an LAE.

hy there....can anyone tell me what exactly they will ask during the interview?
i really want to join MIAT....i just got 6A and 4B in my spm.....i dunno whether my result was good or not.....can anyone help me?
one more thing....wat about the fees?
i read from the web.....rm10000 for 1 years.....wow!
any scholarship or loan provided for the student?

are you bumi or not?if bumi there is always MARA.
