作者: james1616 時間: 2008-6-21 13:24 標題: AV-8B

Specifications
Contractor:  McDonnell Douglas Aircraft (Airframe Prime), Rolls Royce (Engine Prime)
Power Plant: TAV-8B/AV-8B Day Attack (DA): One Rolls Royce Pegasus F402-RR-406 turbofan engine with approximately 20,280 pounds of thrust
AV-8B Night Attack (NA)/AV-8B Radar: One Rolls Royce Pegasus F402-RR-408A turbofan engine with approximately 22,200 pounds of thrust

Accommodations: AV-8B DA/NA/Radar Aircraft: Pilot only
TAV-8B Trainer: Two seats

Performance: Maximum airspeed: 550 KCAS
Range greater than 142 nautical miles high speed/low altitude combat radius
Maximum range: 900 nautical miles

Countermeasures: Not applicable
Armament: One fuselage-mounted 25 mm gun system
Standard Air-to-Ground (A/G) load: Six Mk 82, 500 pound bombs
Standard Air-to-Air (A/A) load: Four AIM-9L/M Sidewinder missiles
Provisions for carrying up to 9,000 pounds of ordnance on seven stations

Mission and Capabilities: The AV-8B single seat Vertical/Short Takeoff and Land (V/STOL) aircraft is the primary close air support/intermediate range intercept/attack mission fixed-wing aircraft for the USMC and the Spanish and Italian navies.
The AV-8B can carry and deliver an assortment of conventional stores such as the Mk 83 1,000 pound GP bomb, GBU-12 500 pound LGB, GBU-16 1,000 LGB, CBU-99/100 Cluster Bomb Units, and 2.75" and 5" rockets.
The NA configuration includes: night vision goggle-compatible cockpit controls and displays, a wide-field-of-view HUD, a Navigation Forward Looking Infrared (NAVFLIR) system, a Digital Map Unit (DMU), and an Angle Rate Bombing System (ARBS) with laser spot tracker, which provides first pass day or night target strike capability at low altitude/high speed.
The Radar aircraft retains all night attack capability but integrates the AN/APG-65 radar system to extend the tracking capabilities of the aircraft for A/G delivery and A/A defense modes.
V/STOL capability allows the AV-8B to be deployed with ground units using amphibious shipping and/or forward basing for rapid close air support response.

Program Summary: All three variants of the AV-8B are in service with the USMC (deployed in WestPac and the Mediterranean).
The Spanish Navy has DA/Radar AV-8Bs.
The Italian Navy has Radar AV-8Bs only.
The U.S., Italy, and Spain are partners in a collaborative international program.
The original DA AV-8B was replaced by the NA variant in 1990, which incorporated the F402-RR-408A engine and expanded night fighting systems such as NAVFLIR, DMU, night vision goggle capability, and wide-field-of-view HUD.
In 1993, the Radar AV-8B was fielded with the full night fighting capability and an AN/APG-65 Radar set to improve A/G and A/A tactical effectiveness.
In 1994, the U.S. began a remanufacturing process to convert DA AV-8Bs to the Radar configuration (REMAN); deliveries began in 1996.
Currently, a NA/Radar AV-8B upgrade program is underway to incorporate an Automatic Target Handoff System (ATHS) and Global Positioning System (GPS) capability into the aircraft.
ATHS allows direct digital target/mission data exchange between the pilot and ground units. GPS integration improves navigational and weapons delivery accuracy.
The AV-8B has seen service in the Persian Gulf (Desert Storm), Somalia (both U.S. and Italian AV-8Bs), and Bosnia (peacekeeping operations).
A total of 51 Radar Aircraft are authorized for procurement by the U.S., Italy, and Spain.
The U.S. has a planned procurement/delivery program for 73 REMAN AV-8Bs (FY 1996 - 2002).

戰機的短場起降這個名詞早期叫做垂直起降，叫垂直起降很容易引起誤會，以為飛機掛滿了炸彈也可以垂直起飛，其實沒有這個能耐，只有在空機低油量時才能垂直起飛。短場起降英文早期叫做V/STOL (Vertical/Short Take Off and Landing)，現在改叫STOVL (Short Take Off and Vertical Landing)。

短場起降戰機所使用的起降基本原理都一樣，在起飛落地外形時，飛機重心前後各有往上的力量，稱作直接升力(Direct Lift)，用來抵抗飛機重量，這些往上的力量由噴射引擎來提供。前進後退由直接升力往前後小角度擺動來控制，俯仰、滾轉及偏航三軸的控制分別在機鼻、機尾下方往下，左右翼尖往下，以及機尾往左右各有氣閘，氣閘開啟就噴氣，氣閘的氣源由直接升力拉出氣管來提供。有了直接升力及微調用的氣閘，短場起降飛機於是可以像直升機一樣原地上下左右移動。
