Aeronautical Engineering Interview Questions And Answers

reversing the armature terminal is better & applied in
practice.this is becoz of the following drawbacks in field
reversing method.
* high voltage build-up during reversing the field terminal
which is high enough to puncture the insulation of field
coil.

* high flash-over will occur.

* during reversal, the armature current should be limited
to the rated value,otherwise it will draw twice the time of
starting current.we can insert the external resistance to
limit the current while reversing the armature
terminal.whereas,in field reversal we cannot give any
provision to limit armature over current.

aeronautical is not the thing to study it's the thing to
understand the concept that how to fly:-)
obvioulsy in every college aero students are the best one's
in all disciplines

VFD having 3 main section namely Rectifier , DC bus,
Inverter.
by Rectifier input supply AC is converted to DC , In the
section main part is pulse also getting change by no. of
Diodes.

In DC bus section having capacitor , in this capacitor the
power is getting store.

In Inverter section the DC is converted to AC and the supply

There are different kind of people travel in a airlines we dnt know about them? sum people may act violent normally girls soft nature? so the airlines prefer girls y there prefer a beautiful girls? to impress a customer so airline prefer beautiful girls for hostesses

Due to new and utterly inefficient techniques, carbon
dioxide can be broken down into oxygen and carbon monoxide.
this carbon monoxide can then be used to produce plastics
and gas.

Shaock Only at supersonic speed

Message(about aircraft prasence downstream) waves go
upstream at the speed of sound.

But Aircraft goes more than the speed of sound.(supersonic)

Before upstream air get the message about aircraft prasence,
air encouter the aircraft.
No time to adjust the airflow,Hence Shock!

POWER CABLE IS HAVING SOME HIGH MAGNITUDE, IF THE SIGNAL
CABLE YOU ARE PLACING NEARER TO THE POWER CABLE, DUE TO THE
MAGNITUDE (MITUAL INDDUCTANCE) THAT DATA CABLES ARE GETTING
SOME SIGNAL FROM THE POWER CABLE.YOU REMEMBER THAT DATA
CABLE SIGNAL FROM 1.5 VOLT TO 12 V HIGHLY SENSETIVE.THAT
MAGNITUDE ENOUGH TO GENERATE THE TRIGGER VOLTAGE ON DATA
CABLE.THEN SOME WRONG FUNCTION WILL HAPPEN INTO THAT
RELATER CIRCUITS.

yawing motion means the side ways motion aircraft about the
lateral axis.in otherwords side to side motion of aircraft.

ramjet engine

when the external force is applied on the elastic body,the
body will deform from its original position.there will be an
internal resistance force which will act opposite to the
external force with the same magnitude.the internal
resistance force per unit area is called stress.....
pressure is the force which will act normal to the surface
and all over the surface..........

Elastomeric bearings that Elastomeric bearings are bearings
constructed from a rubber type material and have limited
movement that is perfectly suited for helicopter
applications.

simply download naca series cordinates its available on net ..start plotting..tat coordiantes,,,and also templates all available

This is the combined effect low pressure & speed of plane in
sky. Body of aircraft is made up of aluminums due to its
good tensile strength & good conductor.

It is a jet engine with no moving parts, only fuel spayed
and burned.

It jeopardize the accuracy but it also has some advantages
but cannot be used due to its inaccuracy.

Thermal protection system of space crafts will be of tiles
which are made up of ceramics and ceramic composites to with
stand thermal shocks and to avoid cracks it is used as tiles.

Mercury

Under surface of the space shuttle will experience above
2300'c at the time of re-entering.

To overcome obstacle, one should have strong determination
and self confidence on himself / herself. They have to face
life as it comes.

Professional Engineer license is required for people who
aspire to go in as officially approved engineer. The design
specification is done by self employed people or working in
small business. General aerospace engineers work for
government or for big companies and hence few people are not
very keen on becoming PE’s. To become a PE one has to pass
an exam on fundamentals of engineering which takes a\lot of
hours to gruel and work under a licensed PE for about four
years. Also they have to grow through a principle and
practice of engineering exam which requires about 8 hours.

In aerospace engineering there are lots of interesting
topics which include rocketry, aero planes, Lego’s. As a
school student I started sketching for future aircraft and
space craft, military aircraft. I analyzed the importance of
space travel, aviation history, and aerospace industry and
hence decided to get into this field.

Each job profile even in aerospace industry differs from
others. To mainly speak about aerospace there are two
branches or field. One is aeronautical and other is
astronautically engineering.

Aeronautical engineering deals with vehicles which operates
in the atmosphere

Aeronautical engineering deals with vehicles operating in space.

Aeronautical engineering works on tunnel tests, analyzing
flight test data, manned space flights, planning future
space missions, spacecraft operations, designing and testing
robotic systems, developing new propulsion system, computing
optimum flight trajectories, developing communication
systems for distance space probes and designing new rockets.

Astronautical engineer includes designing power systems for
spacecraft structure, developing communications systems for
distant space probes, developing hardware skills for
operations in spacecraft, designing and testing robotic
systems, developing new propulsion systems and computing
optimum flight.

Aerodynamics / performance analysis in military programs
include responsibility like analyzing aerodynamics impacts
which effects from external modifications, developing
mission profiles based on requirements from the customer,
performance data of the mission which includes take off and
landing details, en route and mission data performance.
Analyze the configurations using the dynamics which are
fluid and computational. Additional task may include support
for wind tunnel planning for test flight. Documentation,
test support, data analysis should be done on regular basis.
Co ordination of aerodynamics with multi discipline teams
and data should be provided for support flight management
system or mission planning software.
