Really? FCS or mechanical reliability? Pls elaborate.

Ishyt is def changing with the Trump admin! Not that I'm a Trumpista but recognise that the America First Faction,the patriotic US servicemen in the Pentagon and intel agencies who manufactured his presidency are in the ascendancy over the Zio Elite,tired of fighting endless unwinnable wars for the latter.
Proof of this can be seen in release of previously unmentionable info and hitherto considered 'conspiracy theory,'by the MSM,former fierce guardians of 'the Truth.' Here newsweek goes as far as revealing how the US gov srsly contemplated building Russkie aircraft in a false flag to attack their own bases and blame Russia justifying a war.

The U.S. government once wanted to plan false flag attacks with Soviet aircraft to justify war with the USSR or its allies, newly declassified documents surrounding the assassination of President John F. Kennedy show.

http://www.newsweek.com/us-soviet-aircraft-jfk-docs-cover-operations-717460

In a three-page memo, members of the National Security Council wrote, "There is a possibility that such aircraft could be used in a deception operation designed to confuse enemy planes in the air, to launch a surprise attack against enemy installations or in a provocation operation in which Soviet aircraft would appear to attack US or friendly installations to provide an excuse for U.S. intervention."

History has been made! The MSM has finally admitted the false flag!

Consolidation in the plane sector. First Airbus buys a majority stake in Bombadier C-Series, now Boeing in talks to acquire Embraer.

Another reminder this week of the inherent danger of submarining just as the Argies ended the search for their missing San Juan! An Aussie sub lost for 103 yrs was recovered in PNG waters.

The AE1 vanished near New Guinea in September 1914, with 35 crew aboard from Australia, New Zealand and Britain. It was the first Allied submarine loss of the war, and the first wartime loss for the Royal Australian Navy.

The Aussies have a century plus of sub ops-5 generations of institutional knowledge!? My info about the 35v yr old San Juan is that a decade ago it was basically cut in half in dry dock as they installed new engines. Some of those techs may or may not have properly certified leading to loss of hull integrity.

reliability in IA service

IA dont complain becz that would make them look like fools

u buy equipment without competitive trials , u get short changed in the bargain

A look at the privately developed TeamIndus spacecraft that will journey to the Moon, India's 2nd lunar journey

TeamIndus is launching its spacecraft to the Moon in 2018. This will be the first time any private entity attempts to land on the lunar surface. details on how the spacecraft was built to survive the landing. Meanwhile, here’s an overview of the spacecraft.

The spacecraft has 3 major systems:

Spacecraft Bus: The spacecraft bus consists of the structural skeleton, thermal and propulsion systems.
Avionics: This system houses the on-board computer, power and communications systems.
Payloads: TeamIndus rover ECA, the Japanese rover Sorato (which is piggybacking) and all the Lab2Moon experiments are the major payloads onboard the spacecraft.

1: The structure and thermal systems of the spacecraft
The spacecraft has optical solar reflectors and heat shields to keep itself cool. The lander structure is designed to withstand the impact forces during the launch and landing. The landing gear uses crushable aluminium honeycomb to absorb the impact forces during touchdown on the Moon.
The spacecraft design thus ensures the safety of the payloads and all the subsystems in the spacecraft. The maximum diameter of the spacecraft is decided by the launch vehicle, which is the trusty PSLV from ISRO.

2: Propulsion system
The primary engine on the spacecraft is a liquid rocket engine with a thrust capability of 440 N for major maneuvers. It is accompanied by sixteen small 22 N thrusters for finer orbital maneuvers and directional control.

The propellant is provided by the two helium-pressurized tanks onboard the spacecraft. Hydrazine is used as the fuel combined with Nitrogen Tetroxide as the oxidizer. The propulsion is controlled by the Heater Propulsion Card (HPC) onboard the spacecraft.

3: Power & Communication systems
The three solar panels on the spacecraft are the primary power source, generating 235 W. A 24 Ah Lithium-ion battery is also present for additional power. Spacecraft communication with the control center is handled via the radio S-band and X-band.

S-band is the same channel used by NASA for communication with the International Space Station (ISS). The X-band is used for high frequency transmission as in air traffic control and defense applications. A TM/TC card is used for processing both the data that is sent and received.

4: The on-board computer (OBC)
The on-board computer (OBC) orchestrates the command+telemetry data processing and related operations. The most important job of the OBC is to act as a guidance, navigation and control system (GNC) for the entire mission duration.

5: Payloads
The TeamIndus spacecraft is carrying two of the world’s lightest rovers to the lunar surface. The Indian rover is the ECA a.k.a. Ek Choti si Asha (Hindi for ‘A small hope’), while the Japanese rover is Sorato.The lander will be used to communicate with both the rovers.

both Indian and Japanese rovers will be launched by ISRO PSLV space launcher

thats 8 billions rupees , 133 millions dollar thats very expensive for a radar !

Ah thanks algerian1. $130M for a radar? That's damn much.

come on now

i was trying to make it easy for the mathematician in tdayof

and the fact that i had no idea of the exchange rate

thats not the price of a single radar

thats the amount allocated to buy arudhra radarsssssssssssssss

afaik Arudhra development cost was around 134 crore ie around 21 million dollars only

One of the two Have Blue prototypes sits in a hangar at Lockheed's Skunk Works in Burbank, California in this 1978 photo. The aircraft was the first real "stealth" aircraft, designed to have a radar cross section the size of "an eagle's eyeball".

Lol I'm no mathematician. I detest mathematics, calculus etc. Give me physics, thermodynamics etc

How will you like physics and you don't like maths? That's weird sha.

I can do mathematics well when it's needed but the interest is the issue . Physics mathematics feels like solving real problems but the pure mathematics does not.
