  凭借国产1600KW涡轴发动机,直20拥有比黑鹰直升机更好的高原高温性能
国产1600KW涡轴发动机助直20超越黑鹰直升机珠海航展公开的国产1600KW涡轴发动机
国产1600KW涡轴发动机助直20超越黑鹰直升机国产1600KW涡轴发动机的介绍

  今年珠海航展歼-20和运-20都高调亮相,唯有直-20没有露面,原因可能是前两种飞机都完成了试飞,列装部队,直-20还在紧张的试飞之中,不过它配备的发动机却低调在中航发动机展厅中展出,给人意外的惊喜。

  在中航发动机的展厅之中,展出一种新型涡轴发动机,展板上面介绍这种新型发动机功率在1600KW,这 种综合了国内外研制经验,结合国内工业基础,立足国内成熟材料和工艺,完全独立自主的研制一型先进涡轴发动 机,这种发动机的性能与国外现役同等级别发动机相当,功率等级和结构安装性可以满足大、中型直 升机的要求。

  对于涡轴发动机来说,它的功率指标有多种,包括最大连续功率、应急功率、起飞功率等,按照比较常见的最 大连续功率来计算,国产1600KW涡轴发动机与美国T700-T6E涡轴发动机相当,后者的最大连续功率大约是1577KW,应急功率为2064KW,在这个状态下,发 动机解除对涡轮转速的限制,让涡轮达到最大转速,从而增加发动机的功率,不过这样的高负荷运转的结果就是对 发动机消耗过,因此这种状态实际上是不可持续的,T700-T6E在应急状态之下只能持续工作30秒的时间。
国产1600KW涡轴发动机助直20超越黑鹰直升机中国陆航装备的黑鹰直升机

  众所周知T700系列涡轴发动机就是是美国黑鹰直升机的发动机,这样我们就可以知道国产1600W涡轴 发动机应该是黑鹰这个级别直升机的发动机,而直-20就是国内对应黑鹰直升机的型号,因此可以推测这型涡轴发动机就是国产直-20直升机的发动机,从这个指标来看,国产新型涡轴发动机的功率实际上要比国内使用的黑鹰直升机功率还要大 ,因此直-20的飞行性能,尤其是高原高温条件下的飞行性能显然要好于国内目前使用的黑鹰直升机。同

  根据相关资料,国内目前使用的黑鹰直升机是上世纪80年代引进,编号S-70C,它是黑鹰直升机的民用型,配备的发动机是T700的民用型号CT7-2D,最大功率在1200KW左右,而当时美国陆军航空兵当时自用的黑鹰直升机配备T700涡轴发动机功率 也只有1100KW左右,中国之所以要求黑鹰直升机发动机要有更大的主要是考虑了在青藏高原使 用。

  青藏高原号称世界屋脊平均海拔在3000米以上,一般而言高度越高,空气越稀薄,而现代涡轮发动机属于 热机,它利用燃料燃烧加热空气,空气膨胀推动发动机获取能量,为飞行器提供动力,而燃烧需要氧气助燃,而空 气越稀薄氧气含量越低,这样燃料就不充分,发动机获取的能量就比较受到限制,提供给发动机的动力就会下降, 结果就是飞行器的飞行高度、起飞重量就会下降,因此对于飞行器来说,随着使用高度的增加,它需要增加发动机 的功率,以便抵消发动机效率下降给飞行器性能带来的不利影响。
国产1600KW涡轴发动机助直20超越黑鹰直升机凭借先进的T700发动机,黑鹰直升机长期担任中国陆航 高原直升机的主力

  黑鹰直升机凭借先进的发动机,一直是中国陆航直升机高原直升机的主力,不但国产直升机无法替代,就是俄 罗斯米-17直升机也无法与之相比,直到新世纪俄罗斯为米-17换 装加大功率VK-2500涡轴发动机,这样米-17才具备在中国青藏高原执行任务的能力。而对于国产直升机来说,也需要发动机取得突破,才能打破国外直升 机对于中国高原直升机的垄断,而国产1600KW涡轴发动机就是这样的发动机。

  从这个指标来看,国产涡轴发动机的功率远大于CT7-2D,对标T700系列最新的T700-T6E,这是考虑到了国产涡轴发动机不仅仅要满足直-20直升机上高原的要求,并且要为未来发展留下一定的空间,从国内外通用直升机发展趋势来看,通用直升机增 加的设备越来越多,空重迅速增加,这样就需要增加发动机的功率来抵消飞行器自身重量增加对于飞行性能的影响 ,因此可以想像配备国产新型涡轴发动机之后,国产直-20直升机将会具备良好的高原高温性能,结束国外直升机长期垄断国内高原直升机的局面。
国产1600KW涡轴发动机助直20超越黑鹰直升机先进发动机不但为直-20提供动力,也为中国发展重型直升机提供了发动机

  需要指出的是1600KW涡轴发动机的应用并不仅仅局限于直-20,在美国T-700系列发动机也是AH-64武装直升机的动力,因此利用1600KW涡轴发动机,中国相关单位可以研制一型10吨级重型武装直升机 ,这样新型武装直升机与直-20相配合,加上中俄正在研制的重型直升机,就会形成中国陆航在2020年之后的装备体系,有力的增强中国 陆航的作战能力。(作者署名:小飞猪观察)

As engine aspect is no longer any issue, China must already had proceeded to develop a swing rotor high speed copter in functional equality with Osprey V-22.

I hope they do not follow the ill-fated US layout which crashed so easily and commonly. The idiots made worst than CH-47 Chinook that 2 main rotors are far apart, and not locked on same shaft. This way completely hopeless when one rotor damaged by war or malfunction. The crap immediately out of control totally, spin violently.

May look great in photos but like all PRC crap once they go into mass production they'll be falling out of the sky like Ducks during a the hunting season.

Nothing the chinks make can stand up to the rigors of day to day use. It's all junk.

Yes but that is USA made planes always falling out of sky in the usual news. Not Chinese. Not happening to Chinese.

https://en.m.wikipedia.org/wiki/Accidents_and_incidents_involving_the_V-22_Osprey

June 1991 Edit
A miswired flight control system led to two minor injuries when the left nacelle struck the ground while the aircraft was hovering 15 feet (4.6 m) in the air, causing it to bounce and catch fire on 11 June 1991.[1] The pilot, Grady Wilson, suspected that he may have accidentally set the throttle lever the opposite direction to that intended, exacerbating the crash if not causing it.[4]

July 1992 Edit
On 20 July 1992, pre-production V-22 #4's right engine failed and caused the aircraft to drop into the Potomac River by Marine Corps Base Quantico with an audience of congressmen and other government officials. Flammable liquids collected in the right nacelle and led to an engine fire and subsequent failure. All seven on board were killed and the V-22 fleet was grounded for 11 months following the accident.[1][5][6] A titanium firewall now protects the composite propshaft.[7]

April 2000 Edit
A V-22 loaded with Marines, to simulate a rescue, attempted to land at Marana Northwest Regional Airport in Arizona on 8 April 2000. It descended faster than normal (over 2,000 ft/min or 10 m/s) from an unusually high altitude with a forward speed of under 45 miles per hour (72 km/h) when it suddenly stalled its right rotor at 245 feet (75 m), rolled over, crashed, and exploded, killing all 19 on board.[8][9]

The cause was determined to be vortex ring state (VRS), a fundamental limitation on vertical descent which is common to helicopters. At the time of the mishap, the V-22's flight operations rules restricted the Osprey to a descent rate of 800 feet per minute (4.1 m/s) at airspeeds below 40 knots (74 km/h) (restrictions typical of helicopters); the crew of the V-22 in question exceeded this operating restriction with a rate more than 100% greater.[10] Another factor that may have triggered VRS was their operating in close proximity, which is believed to be a risk factor for VRS in helicopters. Subsequent testing has shown that the V-22, and the tiltrotor in general, is less susceptible to VRS, the conditions are easily recognized by the pilots; recovery from VRS requires a more natural action by the pilot than recovery in helicopters, the altitude loss is significantly less than for helicopters, and, with sufficient altitude (2,000 ft or 610 m or more), VRS recovery is relatively easy.[1]

As a result of testing, the V-22 will have a descent envelope as large as or larger than most helicopters, further enhancing its ability to enter and depart hostile landing zones quickly and safely. The project team also dealt with the problem by adding a simultaneous warning light and voice that says "Sink Rate" when the V-22 approaches half of the VRS-vulnerable descent rate.[1]

December 2000 Edit
On 11 December 2000, a V-22 had a flight control error and crashed near Jacksonville, North Carolina, killing all four aboard. A vibration-induced chafing from an adjacent wiring bundle caused a leak in the hydraulic line which fed the primary side of the swashplate actuators to the right side rotor blade controls. The leak caused a Primary Flight Control System (PFCS) alert. A previously undiscovered error in the aircraft's control software caused it to decelerate in response to each of the pilot's eight attempts to reset the software as a result of the PFCS alert. The uncontrollable aircraft fell 1,600 feet (490 m) and crashed in a forest. The wiring harnesses and hydraulic line routing in the nacelles were subsequently modified. This caused the Marine Corps to ground its fleet of eight V-22s, the second grounding in 2000.[1][11][12]

April 2010 Edit
On 8 April 2010, a USAF CV-22 crashed in southern Afghanistan.[2] Three US service members and one civilian were killed and 16 injured in the crash.[13] Initially it was unclear if the accident was caused by enemy fire.[14][15] The loaded CV-22B was at its hovering capability limit, landing at night near Qalat (altitude approx. 5,000 feet) in brownout conditions, in turbulence due to the location in a gully.[13][16] The USAF investigation ruled out brownout conditions, enemy fire, and vortex ring state as causes. The investigation found several factors that significantly contributed to the crash; these include low visibility, a poorly executed approach, loss of situational awareness, and a high descent rate.[17]

Brig. Gen. Donald Harvel, board president of the first investigation into the crash, fingered the "unidentified contrails" during the last 17 seconds of flight as indications of engine troubles.[18] Harvel has become a critic of the aircraft since his retirement and states that his retirement was placed on hold for two years in order to silence him from speaking publicly about his concerns about the aircraft's safety.[19] The actual causes of the crash may never be known because US military aircraft destroyed the wreckage and black box recorder.[20] Former USAF chief V-22 systems engineer Eric Braganca stated that the V-22's engines normally emit puffs of smoke and the data recorders showed that the engines were operating normally at that time.[21]

April 2012 Edit
On 11 April 2012, an MV-22 from the VMM-261 on USS Iwo Jima (LHD-7) crashed near Tan Tan and Agadir, Morocco, during a joint training exercise, named "African Lion". Two Marines were killed and two others were seriously injured, and the aircraft was lost.[22][23][24] U.S. investigators found no mechanical flaw with the aircraft,[25] and human error was determined to be the cause.[26]

June 2012 Edit
On 13 June 2012, a USAF CV-22 crashed at Eglin Air Force Base in Florida during training. All five aboard were injured;[27] two were released from the hospital shortly after.[28] The aircraft ended upside down and received major damage.[29] The cause of the crash was determined to be pilot error, with the CV-22 flying through the proprotor wash of another aircraft.[30] The USAF has restarted formation flight training in response.[31]

May 2015 Edit
One of three Osprey aircraft participating in a training exercise at Bellows Air Force Station (Waimanalo, Oahu, Hawaii) suffered from dust intake to the right engine,[32] sustained a hard landing with fuselage damage[33] and caught fire. The accident lead to the death of two U.S. Marines, and injuries to 20 others.[34][35] The accident caused Marines to recommend improved air filters,[32] and require reduced hover time in dust from 60 to 30 seconds, although most pilots rarely spend more than 10 seconds in dusty conditions.[36]

December 2016 Edit
On 13 December 2016, at 10 pm, an MV-22 crashed while landing onto a reef in shallow water 0.6 miles (0.97 km) off the Okinawa coastline of Camp Schwab where the aircraft broke apart. All five crew members aboard with Marine Aircraft Group 36, 1st Marine Aircraft Wing were rescued. Two crew members were injured and all were transported for treatment. Ospreys in Japan were grounded the following day.[37][38][39] An investigation into the mishap was launched.[40] Preliminary reports indicate that during in-flight refueling with a HC-130, the refueling hose was struck by the Osprey's rotor blades.[41] On 18 December, after a review of MV-22 safety procedures, the III Marine Expeditionary Force (IIIMEF) announced that it will resume flight operations concluding that they are confident that the mishap was due "solely to the aircraft's rotor blades coming into contact with the refueling line."[42]
