Philip said excitedly: "Wind and Thunder Project, good name!" Doesn't the sound of a jet engine work like wind and thunder? ”

Messerschmik nodded and said: "Yes, everyone go back and prepare well, soon we will enter the substantive development stage, the task will be very heavy, and it will overlap with the M40 transport aircraft development plan." Here, I ask everyone, the success of BFW and the Wind Thunder Project depends on everyone present! ”

After saying that, Messerschmidt was about to bow to everyone, and Philip hurriedly supported his arms with his big hands, and everyone began to say a word.

"Rest assured, Mr. Messerschmidt. We're going to put 100 percent of our energy into it! ”

"That's right! Such a great program that others want to participate in has not yet had a chance! ”

"Mr. Messerschmitt doesn't have to be like this, we promise to get the job done!"

Philip was also touched by everyone's enthusiasm, waved his hands and said loudly: "Everyone, please be quiet! I have something to say! The aircraft of the future will require longer ranges, greater mission flexibility, higher cruise speeds and greater carrying capacity, and military fighters will also need particular maneuverability and agility. In order to meet the development requirements of aircraft performance, the current piston engine performance improvement is very limited, and our jet engine development goal is higher thrust-to-weight ratio, lower fuel consumption, higher reliability and lower lifetime cost. The development of jet engines should comprehensively consider the influence of aerothermal mechanics, structural mechanics, heat transfer, combustion, control and materials on the propulsion system. So the future is bright, but the road is unusually tortuous! ”

Billy said excitedly, "Everyone has confidence, isn't it?" ”

The crowd also shouted excitedly: "That's right! ”

Philip nodded with satisfaction: "The new engine trial production has both the nature of batch production, and the characteristics of single production, with the whole machine test and parts test, the problems in the engine design will continue to appear, to immediately modify the design, in order to ensure that the test can continue to provide the test machine in time, the test machine should take the method of batch production, and implement some major design modifications into each batch of engines, and only make small adjustments and modifications to each engine, Some parts and components even have to go through four or five modifications to finalize, in order to meet the frequent changes, the new machine trial production to adopt flexible production, when the structural change affects the production process or process, can quickly change the tooling fixture, adjust the production equipment, and carry out the production of new structural parts. We need to promote the method of simultaneous design, break the professional division of labor methods in the engine design process, such as the professional division of labor method of aerodynamics, strength, structure, and manufacturing, and divide into groups according to the parts, and the group includes various professionals. From the beginning of the design, the design engineer, the manufacturing engineer, and the application engineer are together to jointly study the design objectives and requirements, determine the technical conditions and process methods, etc., so as to shorten the development progress. Can you understand? ”

Everyone said in unison, "Understood!" ”

Philip looked at Messerschmidt and saw that the master designer was also shocked, so he smiled and said to everyone: "Let's go back and prepare!" I'm going to go back and write the overall plan, and we'll discuss it together when the plan comes out. ”

Seeing that Messerschmidt also nodded, everyone left the office excitedly.

Messerschmitt stopped Philip, who was about to leave, and smiled indifferently: "Philip, why don't you write the overall plan here, and I can also learn it, what do you think?" ”

Philip sat back at his desk and smiled, "Good! Then I'll work with Dr. Wiley on this overall plan! ”

Messerschmidt said calmly: "We are now sure that the thrust of this jet engine is about 1500 kilograms, right?" ”

Philip nodded, "That's right! We want to design it as an axial jet engine. 9-stage axial compressor, ring tube combustion chamber, 2-stage axial turbine, total boost ratio of about 5, thrust-to-weight ratio of about 3, net weight of the engine is controlled at about 550 kg. Let's do it one by one! ”

With that, Philip began to rustle on the paper.

The title is: The overall design scheme of the 1500 kg non-afterburner turbojet engine of the Wind and Thunder Program.

This is followed by the technical data that has been preliminarily calculated.

Maximum take-off thrust: 1650 kg (10500 rpm)

Rated thrust: 1500 kg (9800 rpm)

Pre-turbine temperature: 750 degrees Celsius

Air flow: 27.5 kg/s

Total boost ratio: 5.2

Thrust-to-weight ratio: 3

Weight: 550 kg

Length: 2960 mm

Diameter: 950 mm

Maximum fuel consumption: 1.15 kg/kg/h

Compressor: 9-stage axial flow type. It is composed of a rotor and a stator, the middle casing, that is, the split casing, is divided into left and right halves, the front and rear segments, the front section is made of duralumin alloy, the rear section is made of steel, and the air release window is opened between the 5th and 6th stages, which is controlled by a centrifugal valve to prevent the compressor from working unsteadily at low speeds.

Combustion chamber: Annular tube combustion chamber is adopted, which is composed of an integral casing, a heat shield, 9 flame cylinders and an igniter. The casing and heat shield form an annular airflow channel, in which 9 flame canisters are arranged.

Turbine: 2-stage axial flow type. It is composed of a rotor and a stator, and the two air streams behind the 9th stage compressor are cooled, and the blade body is not cooled, and solid blades are used. A certain amount of cooling air passes between the outer edge plate and the turbine outer ring to form a double-layer outer ring structure.

Fuel and control system: Electrical-hydraulic-mechanical joint control is adopted to coordinate the control of fuel supply and nozzle area. The fuel booster pump adopts a plunger type main fuel pump, and the maximum oil pressure at the outlet is 80 kg per square centimeter.

Lubricating oil system: Adopt closed cycle, composed of lubricating oil tank, lubricating oil radiator, lubricating oil booster pump, lubricating oil return pump, working pressure 5-35 kg per square centimeter, lubricating oil consumption is not more than 0.5 kg per hour.

Starting and ignition system: including starting fuel part, electrical and control part, which is composed of starting generator, starting oil transfer ring, starting electromagnetic valve, starting fuel injection igniter and starting control box installed on the aircraft. 1 starter ignition coil and 4 gasoline starter igniters, indirect ignition in the main combustion chamber.

Cooling and anti-icing system: direct induction compressor 9th stage rear air cooling of the main combustion chamber and turbine section, 9th stage compressor rear air intake cone and front casing support plate leading edge anti-icing.

Installation section: There are 3 support points on the main engine, left and right support points and lower support points, which are used to bear the thrust and most of the load of the engine.

Test: more than 500 hours of ground test and more than 200 hours of installed test flight.

Lifespan: 100 hours for overhaul and 200 hours for total life.

Watching Philip write out the overall plan while calculating, Messerschmidt also showed admiration, and when Philip finished writing the overall plan for the jet engine in one go, Messerschmidt picked up a thick dozen pages of paper, trembling his hands and said: "Philip, this is really a great design plan!" ”

Philip stretched to relieve his fatigue, and then said calmly, "Then ask Dr. Willie to come up with a name for this engine!" ”

Messerschmitt thought for a while and said: "By the way, the development code is called ME15, as for the name, I think the Wind and Thunder series jet engine, how about it?" ”
