McDonnell Douglas F-15 Eagle

F-15 Eagle Production and Development

In 1967, the United States Air Force requested the design of McDonnell Douglas aircraft to fit the demand for a committed air superiority fighter.

In July 1972, the first F-15 Eagle (F-15A) fighter aircraft took its maiden flight.

After a year, in July 1973, the F-15B made its first flight. It was then delivered in November 1974.

In January 1976, the first F-15 Eagle intended for combat mission was deployed.

The F-15 Eagle is one of the most victorious present-day fighter aircraft, with a record of one hundred wins and zero loss in terms of aerial battle, with the major part of the kills by the Israeli Air Force.

F-15 Eagle Design

The F-15 eagle is equipped with a semi-monocoque fuselage with a length of 19.43 meters. It has a large-cantilever wing mounted on the upper part of the fuselage, with a wingspan of 13.06 meters, a wing area of 56.5 square meters, and a 45-degree sweep-back angle.

Ailerons and flaps are positioned on the trailing edge. The empennage is made of metal and composite, the vertical stabilizers were made of aluminum and composite material honeycomb construction, and the horizontal stabilizer of composite. The aircraft is designed with a retractable tricycle landing gear, and has a wheelbase of 8.7 meters.

The maneuverability of the aircraft is based from low weight to wing area ratio with a high thrust to weight ratio, warranting it to pivot firmly without having to lose airspeed. At a definite speed, the dynamic thrust output of the engine is higher compared to the weight and drag of the aircraft, making it capable to speed up vertically.

F-15 Eagle Flight Deck and Avionics

The F-15 Eagle has a multi mission avionics system that makes it special among other fighter aircraft. This system features a Head Up Display (HUD) that provides data without needing the pilot to look away from their accustomed viewpoint, an advanced radar, an Inertial Navigation System (INS) with accelerometers and gyroscopes, flight instrument system, Ultra High Frequency (UHF) radio, a Tactical Air Navigation System (TACAN) that produces exact geographical fixing of the position of the aircraft, and Instrument Landing System (ILS) receivers.

The aircraft is also equipped with tactical Electronic Warfare System (TEWS) that aids the user in tactical decision making by collecting the information of the opponent’s communications with the use of an Electronic Support (ES) system. It has an Identification Friend or Foe (IFF) System that detects if the aircraft is an opponent, an Electronic Countermeasure (ECM) device to deceive detection systems, and a central digital computer.

F-15 Eagle Engine and Performance

The F-15 Eagle is powered by two P&WF100 after-burning turbofan engines. Each engine has a maximum thrust of 23,770 lbf with afterburner.

The aircraft has a service ceiling of 65,000 feet, rate of climb of 50,000 feet per minute, combat range of 1,061 nautical miles and a ferry range of 3,000 nautical miles. It has a maximum speed of 1,433 knots at high altitude.

F-15 Eagle Notable Accidents and Incidents

On May 1 1993, an Israeli Air Force F-15D crashed in mid-air with an A-4 Skyhawk while on a training flight. The right wing of the F-15 was nearly ripped off completely. In spite of the damage it went through, the pilot of the aircraft was able to get to a neighboring airbase and land smoothly. There were no recorded fatalities in this incident.

On March 26 2001, two United States Air Force F-15C collided while on a low flying training close to the summit of Ben Macdui in Scotland. Both of the pilots died on the accident.

On November 2 2007, an old Missouri Air National Guard F-15C crashed close to St. Louis, Missouri. Initial finding was because of the possibility of a structural failure of the aircraft.  There were no recorded fatalities in this incident. On the next day after the incident, the USAF suspended all non-mission critical F-15 operations.
