McDonnell Douglas (now Boeing) F-15 Eagle Air Superiority Fighter



DESKRIPSI:

Dengan tujuan untuk melakukan penggantian pesawat F-4 Phantoms, AU AS mengeluarkan kebutuhan pesawat baru dengan jenis pesawat tempur superioritas udara jarak-jauh pada 1965. Performa yangdibutuhkan adalah kemampuan udara-ke-udara visual, kemampuan "dogfight" jarak dekat, mesin kembar, meriam internal, mempunyai jarak jangkau yang jauh sehingga dapat ke Eropa tanpa proses pengisian bahan bakar, dan kecepatan maksimum hingga 2.5 Mach. McDonnell Douglas dipilih dari rivalnya North American and Fairchild Republic untuk memproduksi pesawat yang kemudian dikenal dengan F-15 Eagle.

McDonnell Douglas menggunakan sistem aerodinamik yang memberikan F-15 sayap yang besar/lebar sehingga pesawat mempunyai agilitas baik untuk pesawat sebesar F-15. Akan tetapi, masalah "buffet and flutter" transonik yang terjadi pada penerbangan test awal sehingga memputuhkan rem-udara yang lebih besar, memotong "trailing edges" pada ujung sayap dan menambah "notched dogtooths" pada ekor pesawat. Penambahan inlets adjustable kompresi eksternal dan penggunaan titanium pada skala besar membuat F-15 dapat mencapai kecepatan 2.5 Mach pada altitude tinggi, tetapi kecepatannya hanya terbatas sampai 1.78 Mach ketika dipersenjatai. Desain kokpit revolusioner milik F-15 menghasilkan visibilitas bagus dengan menempatkan pilot di bawah atap/kanopi besar dan penggunaan Hands On Throttle and Stick (HOTAS) menempatkan semua kontrol vital pesawat dekat dengan tanga pilot.

Walaupun AU AS sebenarnya memesan 730 pesawat F-15A tempat duduk tunggal dan F-15B tempat duduk dua untuk trainer, hanya 410 saja yang telah dibuat, sebelum produksi dirubah menjadi model F-15C/D yang lebih baik. Pesawat model C/D ini mempunyai sebuah receiver peringatan radar baru, update software dan tangki bahan bakar konformal sepanjang samping inlet mesin yang meningkatan kapasitas bahan bakar tanpa mengganggu kapasitas senjata. Model F-15C/D juga mempunyai mesin F100-220 yang lebih bertenaga ditambah dengan radar APG-70 yang lebih cepat dengan resolusi yang lebih baik dan memori yang lebih besar disbanding dengan radar terdahulu, APG-63.

Model F-15A/B dan F-15C/D juga diupgrade mengikuti ambisi Mid-Service Improvement Program (MSIP), dengan mengupgrade radar, sistem avionic, dan mengganti komputer analog dengan prosesor pusat digital. Selain itu, dengan penambagan layer display senjata, meningkatkan countermeasures internal dan penambahan kompatabilitas dengan AIM-120 AMRAAM.

Pesawat F-15A/C mulai digantikan dengan F-22 pada sekitar 2010 dan pesawat yang tidak diganti akan dirubah untuk digunakan sebagai pesawat kejut pertahanan udara.
