Ndege inaweza paa injini ikizima angani??

[nimesota]

na wewe unahoji kama nani? au wewe ni Michelle? hovyo kabisa wewe.

hahahaa dah

Bado sijapata somo nadhani wale manguli wanahitajika kupatia darsa hapa.

Kazi ya engine ni kusukuma ndege iende mbele. Kuelea Angani kunasapotiwa na umbo lake.

If that is what u mean, then you're wrong.

kuna kichumba special kwa rais,ndege ikipata hitilafu na haiwezi okolewa wanamkimbizia humo,kisha chumba kinajidetach(kujitenga) na ndege na kuanguka pekee yake kikiwa suppoted na miamvuli kupunguza kasi ya impact kitapoanguka chini.

Mkuu yaani hili suala huwezi kuliguarantee mana zunguka popote pale wanakwambia other remained as closed secret, watakuonyesha tu kwamba ndege ina ina Vyumba vitano.
Labda kile kilicho mbele kule chini ya marubani kiwe kinaweza kujidetach napo hatuwezi pata proof mana nichumba kinachojulikana kwamba ni cha Raisi.

Jamaa ndege yao engine zinapiga kazi kwenye condition zote, kwenye september 11, walitaka kumkimbiza Bush akatulie angani mpaka hali ikae sawa pale us, kwahiyo ina uwezo wakuruka Futi 4500 nakuanza kuzunguka juu ikiwa imetulia.

The Tomorrow People, ymollel kakujibu vizuri.
Ni kama vile gari ikizima ingine katikati ya safari, depending on the acceleration speed iliyokuwepo ni ujanja wa dereva tu kuisukuma mbele zaidi na kama hamna jam basi ndo kabisaaaa unaburuza tu mpaka mbele zaidi.
Ni hayo tu

na wewe unahoji kama nani? au wewe ni Michelle? hovyo kabisa wewe.

Kwa akili yako nyeupe unadhani utapewa mfumo wa ndege muhimu kama ile?...
Utakachoambiwa ni kile ambacho dunia nzima inajua...

 

[Konda wa bodaboda]

Momentum yake iliiwezesha kuendelea na safari, pia kiwanja kilikuwa karibu. Pia kufeli kwa injini hakumaanishi kwamba kila kitu kinafeli.

Injini ni chanzo cha nishati ya kuwezesha chombo kifanye kazi, sasa unaposema injini ikizima mitambo mingine inafanya kazi, swali hiyo mitambo mingine inatoa wapi nishati kuwezesha kufanya kazi?

ENGINEERS walishaliona hilo, so injini ikifeli ndio hata milango isifunguke au mbawa zisiweze kubadili mwelekeo, au mawasiliano yakatike.....?

Wakuu habari!!
Wiki iliopita niliona documentary Nat Geo. Kuna ndege ya Canada 2001..ikiwa na abiria ilipata hitilafu angani na injini zote zilizima lakini pamoja na hayo iliweza kutembea kilometre 100 na kutua Salama uwanja wa ndege.

Sasa sijaelewa ni ilikuwaje ikafanikiwa kuendelea na safari bila injini???

Naomba kujuzwa.

wengine ndege yetu ni treni ya kati na tukijitahidi sana basi la kimbinyiko sasa ndugu yetu unatuuliza kuhusu mbun'go ( ndege ) siyo matusi haya kwetu kweli?

 

[p.col]

to control direction ya ndege lazima engine iwe inafanyakazi, so kama ilizima angani only gravity and initial velocity (velocity at the moment the engine stopped) will determine its destination, kwa case hiyo nadhani lengo la hiyo documentary ni kuonyesha huo muujiza

na pia hata hydrolic system inaweza kuwa active kwa muda kiasi. hadi stored pressure itakapoisha. hii ni kwaajili tu ya rescue.

Ninachoongea nilitoa askcaptain.com kuwa kama ndege ikizima angani, rubani bado anakuwa na uwezo wa ku-control flaps, wings nk hivyo kumwezesha kutua salama ila si kwa umbali mrefu sana.
Na pia anasema kazi ya engine ni kuisukuma ndege mbele.

Upo sahihi mkuu, na hicho ndio hata mimi nilichomaanisha tangu mwanzo. Na hata,nilipo google nimekikuta kwa captain. Nilitumia fikra ndogo tu kwa kulinganisha gari inapozima wakati linatembea, hydrolic ndio msingi wa control ambapo injin ikizima unaweza kuendelea na starring, brake na clutch hadi pressure itakapoisha.

Ndege yoyote ile inapaa kwa uwezo wa engines zake.Kama engines hazifanyi kazi haitapaa kamwe.Hapa lazima kutofautisha ndege ikiwa angani ambapo tayari inakuwa kwenye mwendo na ndege ikiwa kwenye runway tayari kuruka.Kinachoipaisha ndege angani ni msukumo wa engines zake kwa kuhusisha shape ya ndege ambayo imetengenezwa ili iweze kuelea hewani (aerodynamic) na zaidi sana flaps zinazodhibitiwa na rubani ili ndege iwe kwenye mwelekeo unaotakiwa.Ndege iwapo angani huwa inasukumwa na engines zake,Kama engines zote zikiacha kufanya kazi inaweza kuelea hewani kwa muda kwa kutumia ile speed iliyotengenezwa na engine zake kabla ya kuzimika.Hii ina maana rubani anaweza kutumia speed hiyo kuishusha ndege na kutafuta sehemu ya kutua kwa dharura.Kuna kitu kinaitwa ''Gliding'', Hiki ni kitendo cha ndege kuelea angani kwa muda fulani bila kuwa na msukumo wa engine.Mfano mzuri wa Gliding ni kama uonavyo yule ndege 'eagle' anapokuwa juu sana angani huwa hapigi mbawa zake ila huwa anaelea angani kwa kutumia ile momentum aliyoitengeneza awali ili kufika juu.Kurudi chini anatumia utaratibu wa kurekebisha mbawa zake za mkiani ili aweze kutua kwa usalama.Ndege (airplane) pia hutumia flaps ambazo utaziona kwenye mabawa yake pamoja na Rudder ambayo iko kwenye mkia wake kwa ajili ya kudhibiti mwelekeo kulia au kushoto.

Hili weza ku2a salama, kutokana na speed iliyo kua nayo, nadhani ilikua 270klm/h and above hivyo kufanya ku2a bila shida na engine zkiwa off.

Swali lako limejibiwa na Captain mwenyewe hapa.

Dear Captain Lim,

If an airplane encounters all engines failures during the flight, what will happen? Does the plane start flipping and crash, or it continues to fly while losing height, and how long does it last and how safe is to land?

Raid Asfour,
Australia

Hi Raid,
This is a very interesting question and I am sure many other non-aviators would be interested.

When all engines are failed during flight, not all hopes are lost my friend ! Have you ever heard of gliders flying ? Well, gliders fly without any engines! Okay, I am being too simplistic. Nevertheless, all aircraft can glide to a safe landing but the degree of distance flown varies. Gliders can stay in the air for a long time. Single engine aircraft encountering an engine failure can also glide a fair distance to execute a safe landing provided it has the height.

I am sure your question concern commercial aircraft. Firstly, I must say that all commercial aircraft engines are very reliable and to have all the two, three or four engines failed totally on them are very, very remote. Of course, I am not going to argue with the Murphy's Law that, anything that can go wrong will go wrong.

Okay, I will tell you a true story or two. In 1983, a Boeing 767 belonging to a major Airline in Canada actually lost all their (only two!) engines in flight. The cause of the failure was not because the engines were technically faulty. It was due to human error ! You see, apparently the engineer in charge of refueling the aircraft interpreted the fuel request incorrectly. The pilot requested fuel uplift in kilograms, which is normal (rather than in gallons or liters) but the refueler read it as in pounds. Remember, one kilogram of fuel equals to about 2.2 pounds. So the aircraft had about half the fuel required to fly the distance. Consequently, the Boeing 767 ran out of fuel halfway and both the engines quitted on them !

Of course, the pilots should have realized the mistake but it was unfortunate that they missed the second chain of events which could have prevented the accident. What was fortunate was that, the pilot concerned used to fly gliders as a hobby. He happened to recognize a disused airfield nearby that he used to land before. He then executed a perfect forced landing without any loss of lives or aircraft.

The second story concern another major Airline from the United Kingdom. Its Boeing 747 was enroute from London to somewhere in Australia when it lost 4 engines due to volcanic ash spewing over the sky near Jakarta in Indonesia.

Fortunately, the crew were able to restart (or relight in aviation term for jet engines) at least 2 engines when they were cleared of the volcanic ash at a very low level.

Your question was, when an airplane encounters all engines failure, does the plane start flipping and crash, or continue to fly while losing height? If it continues to fly, how long does it last and how safe it is to land the aircraft ?

As I have described earlier, the aircraft does not flip or crash. It continues to fly at an optimum gliding speed, a speed much lower than its cruising speed.

However, it may not be able to maintain its cruising altitude but continues to lose height at a rate of about 3500 to 4500 feet per minute. This will give an aircraft, cruising at 35,000 feet about 10 minutes to fly a distance of about 40 to 50 nautical miles. Remember, pilots have been trained to restart/relight the engines whenever they encounter total engine failures. If restarting the engines were unsuccessful, they would have no choice but to carry out a prepared forced landing - just like what the Canadian pilot did to the crippled Boeing 767.

If you were a passenger on board this ill-fated aircraft, how would it feel like ? Although I have never encounter such an experience as a passenger, I have practiced this exercise many times and have been tested thoroughly in the aircraft simulator.

This is what will likely happen if you are in the passenger cabin. Firstly, if both engines failed simultaneously (very, very unlikely, but normally one after another), the noise level will drop very rapidly. The cabin lights will flicker and may be a bit dimmer. If the aircraft auxiliary power unit (something like a standby generator-cum compressor) fail to start automatically, you will feel the slow depressurization in your ears. Oxygen masks will drop from the ceiling and an automatic emergency announcement will be made through the Public Address System shortly. The cabin crew will then brief you the emergency procedures for a possible Forced Landing or Ditching.

How safe is it to land ? In a Boeing 777, with both engines failed, it is still controllable even though most of the normal hydraulic system pressures would be lost. However, there is the emergency hydraulic pressures generated by the Ram Air Turbine system (RAT). The RAT will automatically extend when it senses both engines had failed. There are fan blades on the RAT which will turn to generate hydraulic and electric power as the aircraft glide forward at a speed of about 180 to 280 mph. The landing gears would be extended by the emergency alternate system and the aircraft has sufficient brake pressure to bring the aircraft to a complete stop using the emergency accumulator pressure.

In a nutshell, if an airplane encounter all engines failures, it is capable of gliding to a safe landing provided there is a suitable landing area. The landing gears would extend and the brake would still function to stop the aircraft safely. So all hopes are not lost !

Hope that answers your question.

Sijapinga sentence yako yote.
ila ulipomalizia kwamba kuelea angani ndege inasapotiwa na umbo lake ndio uongo ambao wajinga watakubaliana nao.

Tukiilusha ndege juu alafu tukazima engine unazani itaendelea kuelea au itashuka ?
Jaribu kufikiria kidogo.
bila engine ndege ata iwe na streamline body la aina yeyote haiwezi kuelea juu, itashuka tu, mana sio puto lile.
Swala la engine kuwezesha ndege kwenda mbele halpingiki. Ila ndege ikizima angani haitaweza kuendelea kuhang tu, lazima iende chini taratibu
