プラット・アンド・ホイットニー R-2800

(プラット・アンド・ホイットニー ダブルワスプから転送)
R-2800(通称:ダブルワスプエンジン)は、アメリカのプラット・アンド・ホイットニーによって開発・製造された空冷二重(複列)星型18気筒の航空用エンジン。第二次世界大戦期において、F4Uコルセア、P-47サンダーボルト、F6Fヘルキャットなどのアメリカの主力戦闘機やA-26インベーダーなどの爆撃機に採用され大いに活躍した。
特筆すべき事項として、大出力発揮に比例して生じる往復運動質量起因の二次振動を打ち消すために、クランク軸の前後両端に2倍の速さで逆回転するダイナミックバランサー(慣性平衡装置)を取り付けることでその問題を解決したことが挙げられる。
