V-280實在太大台了 需要的空間太大 同時姿態的變換速率上也有劣勢 感覺就和當初軍方提出的要求有一點本質上的差異 因此輸掉這局好像也不意外

Army FVL programs on pace in FY-22 and FY-23 budgets, Textron executive says

2022/04/28

The company is expecting the Army to announce its decision on the FLRAA competition in early July, Donnelly said Thursday.
The company’s FARA prototype is more than 85% complete.

同家魚鷹可以收翅膀，V280不行
單使用空間這點就必敗了

魚鷹收翅膀的能力帶來的代價不小
魚鷹噸位過高 主翼面積卻過小 兩旋翼其實也過小
導致起降過程中空力性能過於敏感 吃到自己旋翼下洗亂流時會摔下去
這只能靠更謹慎的下降程序來控制 雖然說小主翼小旋翼對極速有利就是了
以艦載機來說 魚鷹的存在是必要的 但代價高了點
V280則是把尺寸重量翼面積等設定改回到傾轉旋翼機的理想值
重現傾轉旋翼機原本該有的優勢隱匿其劣勢 所以我覺得她不太可能改折翼跟上艦
主翼太大 而且大幅增重之後經濟性等優點又會消失
傳統定點懸翔的場合上 SB>1這種構型其實也是比傳統懸翼機差些
對轉懸翼面積較單懸翼小 下洗氣流較大
另外這種航行特化懸翼比較類似定翼 結構上比較偏剛性連結
相對傳統旋翼的柔性連結 垂直起降靈活性也會比較差
不過畢竟就是兩片超大旋翼 應該都還是比V280的強

空軍不會讓陸軍拿回定翼機的
而陸軍至今也拿不到V22

US Army: CH-47F Block II comes with less power than planned

2022/04/08

The innovative ACRB rotor blades made of composite materials were originally developed for the RH-66 Comanche reconnaissance helicopter, which never went into series production.
The new rotor blades should give the Chinook helicopter an additional lift of 771 kg.
Abandoning the new rotor blades could now mean that the modernization program will only offer about one-ton additional load capacity for the future Block II Chinooks - five of which were contracted in autumn 2021.
