There are two blocks of apartments separated by a narrow alleyway. Person 1 is in the middle of the room in Apartment 1 (first floor if you are in the UK and second floor if you are in the USA!) and Person 2 is on the ground outdoors in the alleyway.
If both people speak at the same volume...
Hi,
I have been researching how to protect my card collection from the unlikely event of a house fire, however there is not enough data for me to estimate whether my set up is adequate or not. If anyone could approximate anything here without knowing all the exact variables (r-values) that...
I'm 24 and graduated with a masters degree in electrical engineering in the UK last year. I had it in my head that I would get a masters degree and then get a graduate training scheme position in something like power/energy and enjoy it while earning decent money, but I haven't been able to get...
I'm asking this mainly to engineers but anyone can answer. How important is the classification of degree that you receive and what has it's impact been on your career?
I plan to work in industry and eventually towards chartered/professional status then management positions. For my MEng...
That is an interesting point about 460MJ being equal to about 11kg of fuel, but I did read that an aeroplane uses around 1 ton of fuel taxiing per day which could mean moving on the ground wastes a lot of energy by using the jet engines
This is a University group project and I am looking at the generation section.The plane we're looking at is an Airbus A380 as a base model . The idea would be to use 3 phase AC induction generator(s) and then convert this to DC for the supercapacitors to charge and then use all of this energy to...
I'm doing some research into capturing a large amount of energy over a short period of time. The energy will be stored in supercapacitors but I'm finding it hard to find information on how a generator would cope with this.
My project investigates the feasibility of using a regenerative braking...
I'm doing a regenerative braking on aircraft project and I basically wanted to know what type of motor will be better for using on the planes landing gear to taxi it along the runway.
I know DC motors have better speed control but since the plane is so heavy I'm not sure if even a few DC motors...
I would like to work out the torque required to move an Airbus A380 along the runway to taxi it back to the gate after touch down. I want to look at using electric motors on the wheels to do this
Say the weight of the plane is 400,000kg, the speed required is to be around 10 m/s and the...
The generators used on the main engines on the A380 are variable frequency at 360-600Hz so they can operate at different speeds. Maybe something like that will be able to cope with the landing although they will be much larger.
I'll look at the current technology for regenerative braking in...
I would guess that the initial touchdown will be very unstable like you say especially for the front wheels. I'd also imagine that the huge amount of initial torque generated would be problematic to the generator and I have no idea how a conventional generator would cope with such a high and...
I will do the calculations for for the A380 which I'm going to use as my model aeroplane.
Yes like you said the extra weight is going to be very important so I will be sure to look into the extra fuel required from the weight of the system to determine if it is feasible or not.
Also though...
I'm doing a university project which looks at regenerative braking in aircraft when coming down to land. Around 3MW of power is available when a large plane lands and we want to try and capture some of this by using generators on the wheels to charge supercapacitors, which will feed into...
Homework Statement
Could anyone give me an idea of how to start this problem to work out the resultant force's magnitude, direction and couple in the top (alternator) pulley?
Does the 30° angle affect the equations? As all the notes I have seem to only have pulleys with the force at each...
