Is there any plan for a sub-orbital flight ?

No plans.

Very much!! first all required tech blocks need to be developed then only ISRO will take decision to conduct manned mission.

Do you want more?  ;D

That last one was nice but a little small - do you have larger versions?

ISRO to modify PSLV PS4 (4th stage) into a service module for manned missions.

Update: A concept art of ISRO's Orbital vehicle (right image). It is based on a modified PSLV PS4 stage (left image).

From the concept art, the orbital vehicle will consists of following modules:

1) PS4 stage + service module 2) crew module

So, if I understand the drawing, the PS4 stage provides all the propulsion (including presumably final insertion and deorbit), while service module is just radiators and solar power?

No plans.

Reverse Flow Multiple Nozzle Solid Rocket Motor prototype Static Test

Crew Escape System (CES) of Human Spaceflight Programme (HSP) calls for the design and development of a different class of special purpose motor. Crew Escape System (CES) is a reverse flow motor with multiple nozzles mounted on the forward end so as to keep hot exhaust gases as far from the crew module as possible. Low altitude Escape Motor (LEM) has to produce enough thrust to pull the crew module away from the launch vehicle within milliseconds of initiation. Low altitude Escape Motor (LEM) is part of a critical system that allows the astronaut in crew module to safely separate from the launch vehicle in the event of an emergency during launch pad operation or in the initial ascent phase of launch. The design of reverse flow solid rocket motor with multiple nozzles is a new and innovative task for ISRO.

I have been looking at what is "out there" concerning the Indian manned programme and I am always left with the question "why?".

Of course, it will allow India to put a couple of people into orbit, circle the Earth and then return to Earth safely.   But if the maiden flight is more than ten years away then India might manage a few trips to ISS before that is disposed of (one way or another).

Maybe they hope to collaborate with the Chinese at that point?   Except that the Chinese will probably be looking at the Moon by the time the Indian spacecraft has finished its test programme.

Maybe by then NASA will have decided what it wants to do with people in space and India might see a role there?

So, what are the Indians going to do in orbit?

Well, it's not like we're going to run out of research topics for a LEO, microgravity lab. The scope for research (and indeed anything) is infinite.

Having said that, I would love, LOVE for wider international co-operation; and for each country to develop its niche.

Gee, why does any country do crewed exploration of space? I bet many at ISRO are enamoured with the exploration of space and would love to explore space with their own astronauts in their own spacecraft. The only thing holding them back from doing more is funding. As this funding comes from the government, a crewed space program is probably done for the same reasons that the US, Russia and China have their own programs. For prestige and pushing the technological capabilities of the country. As a bonus, some scientific research also gets done.

Following on from my earlier post and the response by Steven Pietrobon, some further thoughts.

Yes, the piloted programme could be a political/ego programme for India.   But when they were flying men both the United States and the Soviet Union had plans for where those flights might lead.   While ego was a factor there were plans beyond "put someone in orbit and bring them back after going round the Earth a few times".

Similarly, videos released at the time of Shenzhou 5 indicated a possible plan to dock a Shenzhou with the orbital module from a previous mission (this option was dropped) and then to dock with the space space lab which we now know as Tiangong.

But have the Indians said anything beyond flying people in a can and returning them to Earth?

Yes, they are interested in human Lunar exploration. I haven't seen anything on an Indian LEO space station. Attached is a slide of what they have been studying.

Phase 1 Study: Earth Orbital Mission
Objective: Undertake a Human Space Flight Mission to carry a crew of two to LEO and return them safely to a predefined destination on Earth.

Phase 2 Study: Manned Lunar Missions

Also attached is the summary slide from Aero India 2011

* There are advantages of having astronauts in space rather than utilising unmanned machines alone for space exploration
* There are short term and long term gains from manned missions
* Various new technologies are needed for manned missions
* Human rating primarily concerned with manned safety, can be characterised as a basic approach to the design, testing and operations with thrust on safety of crew

I have seen similar ISRO charts a decade ago with similarly large plans for space development and exploration.

No Bucks, no Buck Rogers. Until the government appropriate actual money for development, this is the same approach as Roskosmos charts showing Russian lunar landing plans.

The program is off the priority list but the planning stage is still ongoing. By 2017 ISRO will have all the basic technology to start a manned space program, then they can get serious about putting humans in space.
