Raytheon Awarded Contract for F-15C AESA Radars
Citat:Boeing Company has awarded Raytheon Company a follow-on contract for the sixth production lot of APG-63(V)3 active electronically scanned array radars for United States Air Force and Air National Guard F-15C aircraft.The original contract from Boeing began in 2007 as part of the F-15C upgrade program. To date, more than 46 radar systems plus spares have been delivered. Production lot six, awarded in March of 2013, includes radar modification kits and spares for the Air Force and Air National Guard.

Na temi Su-27 se pise o potencijalima doleta/radijusa uz odredjeno stanje goriva u unutrasnjim rezervoarima.Pa ajd da malo obradimo ( podsecanja radi ) tu tematiku na temi njegovog glavnog pandana .Kao i u vecini slucajeva imamo vise razlicith podataka o tome .


Dakle kapaciteti/zapremina kako unutrasnjih tako i ukupni sa spoljnim na C i E verziji .

Internal fuel capacity

F-15C 2,070 US gal ( 7,836 liters) - 13,455 lb (6,100 kg)
F-15E 2,019 US gal ( 7,637 liters)

US gallon je ekvivalentan kolicini od 3,785... litara

Max internal and external capacity

F-15C -7,836l + 2x CFT (849 US gallons (3,213.8 L)) +3x 610-US gal /postoje podaci o 600 gal / (2,304-liter) tanks daje total 21188 litara

F-15E - razlika od 199 litara u unutrasnjim ,dakle nesto manje od 21000 l.

Citat:F-15C entered service with CFT capability. Initially known as FAST packs (Fuel And Sensor Tactical), each unit carried an additional 849 US gallons (3,213.8 L) of fuel and were first tested on the F-15B in 1974. All U.S. F-15Es, and Strike Eagle export variants such as the IAF and Singapore models, are fitted with CFT's and require modification to fly without them. The FAST pack was originally intended to carry a navigational and targeting infrared sensor system (thus "Fuel And Sensor"); however, the F-15 simply began carrying LANTIRN pods for ground-attack missions instead

I neki podaci o doletu/radijusu

Max Combat Radius / dakle sa max kapacitetom goriva /

F-15C 1,062 nm (1,223 mi; 1,968 km)
F-15E approx. 1,000 nm (1,150 mi; 1,853 km)

Range 2,500 nm (2,878 mi; 4,631 km)

za verziju C

Ferry range: 3,450 mi (3,000 nmi, 5,550 km) with conformal fuel tanks and three external fuel tanks

za E

Ferry range: 2,400 mi (2,100 nmi, 3,900 km) with conformal fuel tank and three external fuel tanks

Komentar

Citat:The maximal total range is the distance an aircraft can fly between takeoff and landing, as limited by fuel capacity in powered aircraft, or cross-country speed and environmental conditions in unpowered aircraft.

Ferry range means the maximum range the aircraft can fly. This usually means maximum fuel load, optionally with extra fuel tanks and minimum equipment. It refers to transport of aircraft for use on remote location.

Combat range is the maximum range the aircraft can fly when carrying ordnance.
Combat radius is a related measure based on the maximum distance a warplane can travel from its base of operations, accomplish some objective, and return to its original airfield with minimal reserves.

The fuel time limit for powered aircraft is fixed by the fuel load and rate of consumption. When all fuel is consumed, the engines stop and the aircraft will lose its propulsion. For unpowered aircraft, the maximum flight time is variable, limited by available daylight hours, aircraft design (performance), weather conditions, aircraft potential energy, and pilot endurance.
The range can be seen as the cross-country ground speed multiplied by the maximum time in the air. The range equation will be derived in this article for propeller and jet aircraft.
