Patts history

PATTS College of Aeronautics was founded in 1969 as the Philippine Air Transport and Training Services,

a joint venture of Filipino and American pioneers in aviation The primar! aim was to esta"lish a

manufacturing and assem"l! plant for training aircrafts The secondar! aim was to start an aeronautical

school to meet the needs of the domestic and international air transportation industr!

The unfavora"le investment climate at the time constrained the founders to drop the first o"jective and

onl! organi#e and operate an aeronautical school, intended to provide professional and technical training

to its clients The school started with $ne%&ear Airframe 'echanic, Two(&ear Airframe 'echanic, $ne

&ear Power Plant 'echanic and Two(&ear Power Plant 'echanic courses )n its second !ear of operation

the Communication Technician course *Avionics+ and the Four(&ear Aeronautical ngineering course

were added

-nder the stewardship of its .oard of /irectors, the school rose to higher levels of credit and educational

standards )ts .S Aeronautical ngineering graduates regularl! topped the P0Cs 2icensure .oard

3amination for Aeronautical ngineers from its inception in 1945 )n 1949, the school "ecame an

accredited college PATS School grew into a larger educational institution nown as PATTS College of

Aeronautics, adapting the slogan 7Fl! high, !our future is in the sies8

relocated from its old site at /omestic Airport 0oad, Pasa! Cit! to its new home at 2om"os Avenue, San

announced a new diversification polic! PATTS would offer non(aviation related programs responsive to

Jet Fuel HistoryBy James Rada, Jr., eHow Contributor



et Fuel ?istor!

Jet fuel is a specific type of kerosene fuel for aircraft with gas-turbine engines. There aredifferent grades of fuel; Jet A and Jet A-1 are the most popular. Jet fuel is a mix of manydifferent hydrocarbons in varying proportions. t is also designed with a low flash point !11" degrees in military #ets$ to improve ignition.

The First Jet Engines

• The first jet engines were used in World War II by the Germans. Hans von Ohain

built a jet engine that flew a plane on Aug. 2! "#$#. The engine was powered by gasoline.%nglishman &ran' Whittle developed his own jet engine! but it wasn(t used to fly a plane

until )ay "*! "#*". +e,ause of a gasoline shortage ,aused by the war! Whittle(s engine used

'erosene! whi,h remains the base of modern jet fuels.



Improvements

• Though the earliest jet engines ,ould use most types of fuel! as the engines improved

so did their need for -uality fuel. )ore effi,ient engines re-uired fuels that ,ould provide

the power the engines needed. Two of the basi, improvements were higher flash points

temperature at whi,h the fuel ignites/ and lower free0e points. Higher flash points redu,ed

the ris' of fire. As jets began to ,limb to higher altitudes! the outside temperature of the

plane dropped so lower free0e points minimi0ed the ris' of the fuel free0ing.

JP!

• The first jet fuel was developed at the end of World War II. The spe,ifi,ations were

published in "#** and it was ,alled 13" or 1et ropellant ". While the fuel wor'ed! the

military began loo'ing for ways to improve it and thereby! improve the performan,e of its

jets. Other variations in,luded 132 it proved too flammable/ and 13$! whi,h had vapor

lo,' and fuel3loss problems.

JP"

•

13* or 1et ropellant * was a 'erosene3gasoline mi4ture that wor'ed well and wasused by the 5.6. Air &or,e from "#7" until the mid3"##8s. It was similar to the 1et + fuel

used by privately owned planes.

JP#

• 137 ,ame about in "#72. It had a higher flash point! whi,h made a good fuel for use

aboard air,raft ,arriers where fires were always a danger. It ,ontinues to be used by most

navies today. This fuel is also ,alled &3** or av,at.

JP$

• The Air &or,e swit,hed from 13* to 139 in the "##8s! though it was developed in

"#9. It has a higher flashpoint than 13* and is less ,ar,inogeni,. Its formulation is similar

to 1et A3" fuel! whi,h is used by ,ommer,ial air,raft.
