[CORRECTED DB v436]
some low priority change in database (since we talk about paper plane)
Yak-44 and its radar
there is big interview with V.B. Abidin, the leading designer of "OKB Yakovlev " in magazine "Oboronniy zakaz" march 2008 ¹18, article "Eagl eye of the navy:plane of radar surveillance and guidance Yak-44E"
*ozakaz.ru/index.php/articles/15032008/229-n2011-03-28-0338
in russian
in this article is really intresting reference table for example:
Ìain characteristics of the Yak-44E and its RTC (radio-technical complex)
geometrical characteristics
Wing span, m 25.7
Length, m 20.5
Height, m 5.8
Dimensions with folded wings and lowered radome radar m 20.5x12.5x5.7
Wing area, m2 88.0
Fuselage diameter, 2.7 m
Diameter radome radar, 7.3 m
crew
Pilots, pers. 2
RTC operators , pers. 4
(in database 5 crew members can it be corrected?)
powerplant
The type and number of engines 2xTVVD D-27
Take-off power / cruising power, bhp 2x14000 / 6750
Weight without propfan, kg 1650
Specific fuel consumption at cruising kg fuel / bhp*h 0.143
Propfan diameter, 4.5 m
Number of blades propfan 8 + 6
Mass Properties
Weight maximum take-off, kg 40000
Fuel capacity, 10,500 kg
Wing loading, kg / m 2 455
(in database fuel capacity is 8000kg)
flight performance
Maximum speed, km / h 740
Cruising maximum speed, km / h 700
Landing speed, km / h 185
Service ceiling, m 13000
patrol speed km / h 500-650
patrol height m 3000-11000
Ferry range, km> 4000
The length of the runway. m <1350
Duration patrol in the area at altitudes 0,2-11 km and 300 km range. h 3.6-6,5
(well, a lot of incorectness in database it seems)
Radiotechnical complex E-700
Waveband B
The average radiation power. 5 kW
Detection range, km:
air targets (RCS = 3 m2) 250
cruise missiles, AGM-86 ALCM 220
cruise missiles, AGM-84 "Harpoon" 165
Detection range of sea targets such as "destroyer" to the radio horizon
Altitude range detection and tracking of air targets, m 5-30000
Speed range of detectable airborne targets, km / h 40-3500
Number of simultaneously tracked targets 150 on the surfase 1500
The rms error of the determination on the range of 200 km, km:
planar coordinates is not more than 2
a height of not more than 1.5
direction finding accuracy of single director jamming, no more than 20 minutes
Number of induced on purpose fighter 40
The number of operators 4
(here we need a little clarification, from article:
"By November 1979 the OKB AS Yakovlev has prepared a technical proposal for AEW aircraft Yak-44E based at airfields and land on aircraft carriers (take-off from the springboard, landing on the arrester). It considered two alternatives radio complex (RTC), "Torch" (with inside fuselage placing antennas radar - one in the forward fuselage and the second - in the tail), and E-700 (with aerial surveillance radar in a rotating radome above the fuselage)."
" Many problems arose and developers RTC "Torch", which led to delays, and then to end in March 1983, the work on this complex and to a serious reduction of development of the Yak-44E as a whole.
At the same time, since 1982, Design bureau Antonov-based tactical military transport aircraft An-72 been developing in AEW aircraft An-71 for the Air Force. Therefore, for the way out of the difficult situation in March 1983 we decided to develop an alternative design of the ship-based AEW aircraft An-71K by the OKB Antonov. At a basic An-72 to increase the lift of the wing and landing characteristics of both turbojet propulsion D-436K its powerplant were placed over the wing, providing blowing its top surface and mechanization.
To increase the thrust-weight ratio aircraft An-71 is further equipped with a booster TRD RD-38A. Carrier-based aircraft An-71K, to be fitted with three booster TRD RD-38A. The radar antenna RTK E-700 was placed in the mushroom radome on top of the keel, which had a negative sweep on the back and front edges. Preliminary design of the aircraft was prepared for the fall of 1984, it became clear that the geometric dimensions and take-off mass does not allow to place An-71K on the aircraft carrier, and the further development of the An-71K stopped.
In this regard, with the October 1984 OKB AS Yakovlev continued to work on the Yak-44E on the basis of a new design-layout scheme in which there were no PD, and the high take-off thrust-weight ratio and blowing the top surface of the wing to increase its lift ensured turbovintoventilyatornymi engines (TVVD) D-27 (currently, these engines are used on the power unit of the new Russian-Ukrainian military transport aircraft An-70). A new version of the Yak-44E was fitted with RTC E-700 with an antenna radar mushroom fairing above the fuselage as the American carrier-based aircraft E-2C "Hawkeye"."
Sorry for auto translation. So basicly E-700 RTC (for Yak-44)= Kvant-KS RTC (for An-71K)
Number of radio stations:
VHF-UHF band 7
shortwave band 1
satellite communication 1
So could you please change RTC from Shmel-2 to E-700 and and configure other settings
Of course Yak-44 is paper project so not so big priority for this requested changes in database
Few word befor the end of the post. Yes, I know that there is a version (or more accurately preliminary design) of Yak-44 with Shmel-2 for Russian Navy 2010 competition for carrier AWACS(more like competition of preliminary design), and Yak-44 lost that competition to A-110 (obviously, "VEGA" and "Beriev" have a long and very close relationship,there is nothing here to be surprised)so we have more chance to see 4 engine monstrosity of the A-110 than Yak-44 with Shmel-2 in flight
ps sorry for bad english
