Qualification testing of Cryogenic Engine for Gaganyaan Programme

Today, January 12, 2022, ISRO successfully conducted the qualification test of Cryogenic Engine for Gaganyaan programme for a duration of 720 seconds at ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu.

The performance of the engine met the test objectives and the engine parameters were closely matching with the predictions during the entire duration of the test.

This successful long-duration test is a major milestone for the Human Space Programme – Gaganyaan. It ensures the reliability and robustness of the cryogenic engine for induction into the human-rated launch vehicle for Gaganyaan.
Further, this engine will undergo four more tests for a cumulative duration of 1810 seconds. Subsequently, one more engine will undergo two short-duration tests & one long-duration test to complete the cryogenic engine qualification for Gaganyaan Programme.

Ok one doubt , Does this same engine goes to the actual flight or a new one ??

Commencement of Gaganyaan Mission Specific Crew Training

• Gaganyaan Mission Specific Crew Training has commenced. An Inter-Agency Task Team with members from DRDO, IAF and ISRO had generated the requirements for Crew Training Curriculum. The curriculum was approved by an Apex Committee comprising of senior officials from ISRO and IAF, including Wg Cdr (Retd.) Rakesh Sharma and Air Cmde (Retd.) Ravish Malhotra.
• The three-semester training curriculum will have courses on Human Rated Launch Vehicle, Orbital Module systems, Space Medicine, Launch Complex Procedures, Microgravity Familiarization, Human Rating & Certification, Recovery Operations, Survival Training and related subjects.
• Crew Safety in Gaganyaan mission is one of the important objectives of the training program. Towards this, the crew will be thoroughly trained about the operating environment, risks, warning systems, procedures for nominal and off-nominal situations and emergency escape systems.
• Modern training methods such as Virtual reality simulators, Static Mock-up simulators and health monitoring equipment will be employed during the training. Experienced faculty from Indian Institute of Science, Institute of Aviation Medicine, DRDO and ISRO will be delivering the lectures.

Why Gaganyaan would be delayed by several years

So, we can see G1 mission quite soon this year but second unmanned missions (with all parameters) and first human mission might be delayed.

Qualification testing of VIKAS Engine for Gaganyaan Programme
Today, January 20, 2022, High Thrust VIKAS Engine for Gaganyaan programme has successfully undergone qualification test for a duration of 25 seconds at ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu.
With regard to the Vikas engine qualification for the Gaganyaan Programme, two engines have already undergone tests under nominal operating conditions for a total duration of 480 seconds.
The test carried out today is to verify the robustness of the engine by operating beyond its nominal operating conditions (fuel-oxidiser ratio and chamber pressure). The performance of the engine met the test objectives and the engine parameters were closely matching with the predictions during the entire duration of the test.
Further, three more tests are planned for a cumulative duration of 75 seconds under varying operating conditions. Subsequently, another high thrust Vikas engine will undergo a long-duration test for 240 seconds to complete the Vikas engine qualification for Gaganyaan Programme.

Are the grid fins for the Gaganyaan spacecraft? Or the rocket?

Grid fins. Rocket seems to be under production yet.

 

[Maveli]

After further research, it appears that the grid fins are for the crew escape fairing. Those pictures are at least 4 years old. I thought maybe they were part of a Spacex Dragon like reusable rocket.

How much boost in power. Vikas is an old engine. In last upgrade, 10 pc power was boosted if I remember it correctly.

Human-rating I think is more about stabilisation, reliability and velocity reduction as safety is paramount here.
So, I don't know whether they have increased any power besides this.
