In aviation, AVCO is associated with the Lycoming brand (now it belongs to another group: Textron) (see both Textron, and Lycoming).

-Avco has four divisions in the aviation industry:

-Avco Everett Research Laboratory that performed jobs with one megawatt "magnetohydrodynamics" powerplants.

-Avco Lycoming Williamsport where they built piston engines, with a tremendous range of general aviation engines. (see Lycoming).

-Avco Lycoming Stratford where they manufacture gas turbines.

-Avco Lycoming Greer, Carolina del Sur, not well known. This division was initiated by Avco-Lycoming in August 1982 to manufacture parts for the Avco Lycoming Stratford and Williamsport divisions;

Avco Everett Research Laboratory.

-Below we show some schematics of the "magnetohydrodynamics" powerplant.

"Motor Avco-Everett"

-Avco Lycoming Williamsport

"Avco-Lycoming 4-cylinder"

-Just over half the world's general aviation uses engines of this brand.

-The most common displacements have been, from the initial stage, 145, 160, 235, 245, 290, 320, 340, 350, 360, 365, and 390 cu.in. These engines had four horizontally opposed cylinders.

-The 6-cylinder engines had the following displacements: 402, 435, 480, 540, 541 cu.in. The 580 cu. in. engines had 4 or 6 cylinders according to the model.

-The 720 cu- in. engine had 8 cylinders and the 1230 one had twelve. This in addition to major prototypes.

-All these Lycoming engines could have injection, carburetor, turbo, supercharger, gearbox, and some of them went upright or were adapted for acrobatics.

-For more details please see the “Lycoming” chapter.

"Avco-Lycoming 6-cylinder"

-Avco made manufacture agreements with Italian Piaggio for the 435 and 480 engines to use them on training aircraft.

-The same with “BMW Triebwerkbau” for the 480 with gear for the Dornier Do-27 and Do-28 aircraft.

-In 1963, Avco bought the French Potez factory, to be renamed Potez-Avco, distributing the American engines with the intention to manufacture some models by 1966, but not any realization of the 235, 290, 320, 340, 360, 435 and 540, which entered into the agreement, is known.

-Over time, the story ended because of the constant general aviation recession and absence of any new aircraft projects with piston engines that could encourage the industry.

"Avco-Lycoming with John Deere"

-Between the agreements and collaborations there is an interesting one with agricultural machinery manufacturer, "John Deere", in which both jointly developed a Wankel-type rotary engine with turbocharger and gearbox.

Avco Lycoming Stratford

-This is the turbine division of Lycoming in Stratford, Connecticut.

-It is known as “Div. Stratford”. There they build the T-53, T-55 and the ALF-502, as main products.

"Lycoming ALF-502"

-The ALF-502 turbofan is destined for commercial aircraft, such as the BAE-146, and for business aircraft.

-The gas generator is the T-55 core.

-It is considered ultra-quiet and is in the range of 7500 lbs. of thrust.

-The ALF-502 in its military version, when installed in the Northrop A9A, was the F-102.

-The LTS-101 (LTS = Lycoming Turbo Shaft) delivered around 600/685 SHP in various helicopter versions.

-The LTC-1 is the US Military T-53, a free turbine turboshaft. The LT-101 is the T-702.

"4 motores LTS-"

-The turboprop version is the LTP-101 (LTP = Lycoming Turbo Prop) that delivers 620 to 700 EHP.

"LTP-101"

-Avco-Lycoming and Pratt & Whitney have teamed up to develop the T-800 of advanced technology based on the PLT-34 with 825 SHP.

-Also with GE -General Electric- and since 1987, there are agreements to develop gas turbines. The first engine that they developed together was the GE-38.

From appendix 6: From Popsci (Popular Science Magazine) we obtained more information about the MHD engine that is mentioned in the beginning of the main text..

-Known as MHD (Magneto-Hydro-Dynamic) it continued to be developed at Avco Everett Research Laboratory, close to Boston, Massachusetts. The one from the 1970's that we are showing below already is Mark V.

“MHD tests at AVCO” (PiP)

-Below we show the combustor that was tested in the late 1970's at Avco Everett Research Lab. Inc., an Avco division.

-Other companies like GE also investigated on MHD with similar solutions.
