Chapter 060 F-15E "Strike Eagle"

Hearing Jin Shao's words, Zhou Wenwen was stunned for a moment. When he was about to say, "Most of this thing is made of plastic and it's delicious."

"It's edible, and I guess it's delicious."

If Zhou Wenwen remembers correctly, like many fighter jets, the fuselage of the F-15 fighter jet is an all-metal semi-monocoque structure, and the fuselage consists of front, middle and rear sections.

The front section includes the head radome, cockpit and electronic equipment compartment, and the main structural materials are aluminum alloy and composite metal.

The middle section is connected to the wing, and some titanium alloy parts are used to bear large loads, accounting for about 20.4% of the weight of this section. The first three frames are aluminum alloy structures, and the last three are titanium alloy structures.

The rear section is a titanium alloy structure engine compartment, and the zigzag leading edge of the flat tail is a full-motion flat tail, which is large in area and can meet the needs of high-speed flight and maneuvering.

The F-15 wing design adopts a cut-tip delta wing shape, which can improve the wing structure and increase the internal volume of the aircraft. At the same time, it can make the increase of the aircraft's resistance in the transonic region become more gradual, and the focus movement of the aircraft at transonic speed is also larger. small, reducing the trim resistance.

In order to improve the subsonic performance of the aircraft and consider the weight, manufacturing process and system complexity, the F-15 adopts a non-leading edge maneuvering flap and a leading edge fixed conical torsion design, the leading edge is swept back 45 degrees, and the relative thickness of the wing is 6%/3% (root/tip) without the leading edge maneuvering flaps, which were widely used at the time.

The F-15 wing adopts an aspect ratio of up to 3, with a root-to-tip ratio of 5, which is conducive to delaying the separation of the wingtips and significantly reduces the induced resistance of the wing.

The larger aspect ratio increases the **** of the wing lift line and improves the wing lift characteristics.

At the same time, the aspect ratio increases, and the supersonic zero-lift drag coefficient also increases, increasing the trans/supersonic wave resistance.

This shortcoming is compensated for by the use of powerful engine thrust and other aspects of design.

The wing area is 56.48 square meters, the dihedral angle is 1°, and the installation angle is 0°. There are only four control surfaces on the wing, the trailing edge high lift **** and the ailerons.

The F-15 wing structure is a multi-beam torsion-resistant box-type damage safety structure, the front beam is aluminum alloy, and the rear three beams are titanium alloy.

The lower skin of the inner integral fuel tank is made of titanium alloy panels, and the rest are aluminum alloy machined integral panels.

The front and rear edges of the wing, **** and ailerons are all aluminum honeycomb sandwich structures. The damage safety structure of the wing, combined with the load-bearing skin, can support the aircraft to continue flying as long as one wing spar is still intact, which greatly improves the survivability of the aircraft.

The F-15 vertical stabilizer and tail are both honeycomb panel skins and sandwich structures composed of boron fiber composite materials, titanium alloy torsion boxes, full-thickness aluminum sandwich cores and boron-epoxy composite panels.

The torsion box of the two is a titanium alloy structure, and the front and rear edges are an all-aluminum honeycomb structure.

The rudder features carbon fiber-epoxy composite beam ribs and boron-epoxy panels and an aluminum sandwich skin. Both the horizontal tail and the rudder can be interchanged left and right.

The vertical tail is designed with a large aspect ratio and a medium sweep angle. The leading edge sweep angle is 37°, and the camber is 2°. The height is relatively large. Under the high angle of attack, the aircraft's heading stability can be significantly improved, thus ensuring that the F-15 can Effectively conduct high angle of attack maneuvers.

The flat tail is designed with a large swept full-motion low flat tail, with a leading edge sweep angle of 50°, with a leading edge serration and a beveled wing tip design.

The model of these four F-15 Eagle fighter jets, considering the times, Zhou Wenwen believes that it should not be the F-15E that was equipped in large quantities in order to save Boeing in 2020 and 2021, nor the F-15SA.

F-15E, F-15E "Strike Eagle" is a two-seat supersonic all-weather fighter-bomber designed by McDonnell-Douglas on the basis of F-15 with the main task of ground attack.

This is the F-111 successor aircraft developed and put into production according to the US Air Force plan in 1982. It has both ground attack and air superiority capabilities and is called a dual-mission fighter.

The aircraft is basically the same as the F-15D in appearance, the fuselage structure is strengthened, and the engine compartment, cockpit and part of the structure are redesigned, which increases the range by 33%.

Focus on improving avionics equipment, including replacing APG-70 radar and installing Blue Shield pods to ensure target discovery and identification and improve weapon firing accuracy. The original two-degree analog CAS has been improved to have automatic terrain following capabilities. Digital three-degree fly-by-wire flight control system and advanced electronic cockpit display system[, switch to ring laser gyro inertial navigation system, etc.

The weapon pylons have been doubled. In addition to the original pylons, there are 6 pylons beside each conformal fuel tank. The later engine is upgraded to F100-PW-229.

F-15SA, F-15SA is equipped with AN/APG-63(V)3 active phased array radar, advanced digital electronic warfare and radar warning suite, the latest cockpit display system, and can carry "Tiger Eye" ( TigerEyes) infrared search and track system.

Since this type of aircraft has added 2 outboard hardpoints under the wings (No. 1 and No. 9 hardpoints~www.wuxiamtl.com~) to compensate for the resulting reduction in combat flight stability, Boeing Co. A model-based fly-by-wire (FBW) flight control system is used.

The system also reduces the weight of the whole machine, improves the reliability of the flight control system, and also improves the dispatch rate of the aircraft.

And if the model of the four F-15 Eagle fighters is not F-15E or F-15SA, then the answer is only F-15A, F-15B, F-15A/BMSIP, F-15C, F-15D, F-15C/DMSIP.

Zhou Wenwen remembers that the F-15A is a single-seat air-to-air combat version of the F-15 fighter, equipped with the F-100-PW-100 engine and AN/APG-63 radar. It first flew on July 27, 1972 and flew in 1974. Delivered in November.
