Background

Despite the "peace agreement" signed after our "Operation Steel Hammer" against-
school bullies, we realized that school elite guards might also be the one who
we will up against. The school elite guards are led by Mia Alexandra, our curr-
-ent school student union president and leader of "league of honor student", this
group possessed modern armaments , and well trained forces , consisting of merce-
-naries, employed by Mia's corporation and several hundreds of well trained students
from school's well funded combat (including martial arts) clubs .

These forces are more mature, better armed and equipped than our newly formed forces
of street childrens, homeless US war veterans and some Ex-Russian armed serviceman.
Our leader Mark Bernard decide to use the "peace time" provided by the peace agreement
to strengthen our forces, finding better source of fundings and expanding our sphere
of influence overseas, Mark also authorized development of several new advanced weapons
including fighter aircrafts, the results were Shelenia Blanchett and this aircraft.

The Shelenia Etheria , although posses similarities with baseline Su-27M is completely different
aircraft , utilizing our latest know-how on aerodynamics, propulsions , avionics and materials
the design goal is to decisively penetrate school elite guard's F-15 fighters CAP, and to destroy
enemy airborne C4ISR and Electronic attack assets (AEW,RC-135, EA-6B, EA-18G or the EF-111), another
goal is to survive and win combat against any of "top tier" fighters posessed by school elite guards
(F-15,F-16CB60,F/A-18S, Dassault Rafale, F-2A and indigenous "Razorback" fighter). Shelenia Etheria
must also shares some commonality with her "little sister" Shelenia Blanchett, designed for similar
goal but much shorter combat range .

For above mentioned task, Etheria possess the "best we can achieve" performance with low wing loading
and high T/W ratio , she is more than a match for school elite guard aircrafts in dogfight as well
as typical "hi alt BVR Combat regime" where her "Armelia Nieva" AESA RADAR is able to detect 1 Sqm
RCS of school elite guard's Advanced F/A-18S from 300 Km range , and launch our 200km class Maxima
Iradia Long range BVRAAM against it.

The Armelia Nieva RADAR is developed based on Shelenia Blanchett's Celia AESA RADAR, sharing same
module technology and cooling systems . However Armelia Nieva possess larger number of modules
(2200) with larger peak power of 20 watts/ module, bring total Peak Transmitted Power of the RADAR's
to 44 Kw. The RADAR has very low sidelobe of -38 Dbi, thanks to advanced aperture weighting alogarithm
and careful choice of secondary Radome material , to help shaping the beam and to filter out signal with
unwanted frequency and polarization, such as jammers or high powered Microwave based weapon , the RADAR also
have structural mode RCS reduction feature , by utilization of RADAR Absorbent structural materials and
RAM foam , however this came in cost of reduction of available aperture area from 0,79 Sqm to 0,66 Sqm .

The RADAR's processing software are using special, non commercial software BUT with commercially available
high speed processing hardware, ruggedized to reduce suspectibility to EMP or Microwave based weapons as well
as to provide survivability against natural factors might be encountered during maintenance, the RADAR processing
system is capable for up to 175.000.000 MIPS (Million Operations Per Second) , highly competitive against school
elite guard's RADAR processors , the RADAR hardware also provide room for performance growth and additional modes
in the future.

For Passive sensors, Shelenia Etheria is equipped with same "Elda" Multi spectral IRST , capable of detecting
reduced emissivity target (0,36 Sqm Exposed area with 0,15 emissivity constant) at up to 80 Km , the IRST
is capable to image the target in different frequency band (from Long Wave 15 micron IR down to 94 Ghz) ,
allowing target identification and decoy discrimination , the system also able to provide truly passive ranging
method using its different operating band and target's speed , however a laser range finder is also available for
more accurate although shorter ranging than the passive method .

Electronic surveillance system and self protection electronic warfare equipment are similar to Shelenia Blanchett.
However Etheria's Valesca RHAWS system posses more antenna , to provide precision emitter direction finding for
passive targeting of Anti Radiation Missiles on Airborne Jammers or AWACS aircrafts , the system provide full
360 degree capability and precision . However this somewhat increased the total cost of the system over Shelenia
Blanchett's more conventional and optimized precision to detect head on and rearward threats (side is also covered
but less accurate) .

In terms of aerodynamics and materials, Shelenia Etheria combines lightweight alloys,composite materials with
high L/D ratio blended wing body layout and three surface layout with Canard foreplanes and conventional tails
which helps reduce supersonic trim drag and improve maneuver and controllability in High AOA Maneuver . This
aircraft is also equipped with DSI (Diverterless Supersonic Inlet) , reducing weight over traditional variable
geometry inlet but still provide necessary supersonic capability , and to some exent reduce the inlet's RADAR
Cross Section , the inlet is also have S-shaped duct, hiding the compressor face from RADAR's .

The aircraft's nose, instead of Shelenia Blanchett's bulbous ogival nose to maximize RADAR Aperture area , are
shaped similarly to Russian Su-34 "fullback" or "ootkonos"/platypus , this will help reducing nose section's RCS.
relative to "circular shape" nose on typical of our combat aircrafts.

well i think that's all.. :) more to comes later.
