Hindustan Trainer HTT-40

[sasum]

Prototypes or any unpainted aircraft is coated with zinc chromate primer to prevent corrosion. Paint job is done later over these primer coating. It has nothing to do with trainer aircraft alone. It is applicable for all planes. Even prototypes of Tejas has this.

My answer was to the question about YELLOW paint of trainers and not primer which is same for all metal alloys.

The PC-7 Mark II has an unpressurised cockpit. Meaning masks all the way. Flying at high altitude will be uncomfortable. A critical tactical minus in armed version. HTT-40 has pressurised cockpit.This will allow its pilots comfortably during weapon missions over Himalaya like terrain.

The mask provides two critical functions to pilots: it supplies oxygen to them, and it contains a microphone.

The microphone allows them to talk to the other person in the plane (if it's a dual-seater like a trainer), over the radio, and over the intercom (e.g., to ground personnel). You'd have to yell over the roar of the jet engine if you wanted to talk to your back-seater without the mask on. The mic audio is also recorded if it needs to be reviewed later.

The regulator supplies the pilot with breathable air (a mixture of oxygen and nitrogen, the ratio between the two depending on altitude) or 100% oxygen for emergency scenarios. It can also provide a function called partial-pressure breathing for G (PPG), which pushes high-pressure air into your lungs during high-g maneuvers, which increases g tolerance. Why trainer aircrafts can do without mask is clear hear. They can not pull high-g maneuvre, since they have smaller power-plants, nor are they flied above 10000 ft.

In a cockpit above the altitude of 10,000 feet, it would take a little time before pilot starts to feel the effects of hypoxia, so pilots can certainly remove their masks for short periods for comfort. But It's a good idea to have mask facilities even on trainer aircrafts in the event sudden depressurisation of cockpit due to structural damage.
I think HTT-40 in its final version will have oxygen cylinder and mask at least for one person.

Make it armed variant so we can use in naxal areas with little money on fuel and maintenance.

Remember:

“There is no need for [the HTT-40 trainer]”, IAF boss, Air Chief Marshal NAK Browne, said dismissively at the Aero India show in February 2013. “We have the Pilatus PC-7. It’s a proven aircraft. The project HAL plans is from scratch. Our indications are that the cost will be too high. There is no need for all this.”

But then:

Former chairman, RK Tyagi, and the current boss, T Suvarna Raju, threw their weight behind the trainer project and committed Rs 350 crore of internal HAL funds to the development project. A team of young, talented HAL designers worked without IAF assistance to bring the aircraft to flight.

What changed:

Parrikar said: “The young team has taken a calculated risk and they have flown the aircraft within one year and kept their assurance. The indigenous content on HTT-40 is close to 80 per cent. Almost 50 per cent of the components on HTT-40 are manufactured by private players of the Indian aerospace ecosystem. Here, the role of private players and MSMEs has been significant in the production of parts. The IAF is positive in all these developments”.

Result:

Preceding this “inaugural flight”, the HTT-40 had already made its first flight on May 31. Since then, test pilots have expanded its flight envelope, to clear it for flying at 300 kilometres per hour and for 4-G turns. It has validated its glide tests (flying without engines), instrument landing, and demonstrated its ability to land in heavy rain.

In Future:

HAL chairman, Suvarna Raju today: “The project will now go in full throttle as we aim to get the aircraft certified in 2018. Towards this, HAL will be manufacturing three prototypes and two static test specimens”. It is remarkable feat that the aircraft in its inaugural flight carried out low speed pass, a series of turns, high speed pass and short-landing using reverse thrust which is a unique feature available on this engine-propeller combination.”

So was it painful:

The advanced systems in the HTT-40 include a pressurised cockpit (which allows flight at high altitudes), “zero-zero” ejection seats (which allow ejection even from a static aircraft), and a state-of-the-art cockpit display with “in-flight simulation” that permits flight instructors to electronically simulate various system failures, allowing the rookie pilot to handle the “emergency”.

A lab in Bangalore is busy now a days in testing ejection seats.
A new engine CVRDE MANIK(replacing dead project Kaveri) is too progressing well. Hope they succeed.

Manik is a GTRE project. CVRDE works on land vehicles. Manik is for Nirbhaya cruise missile and UAVs etc. It is too small for a fighter jet and certainly not a substitute for Kaveri. K9+ is the substitute GTRE is working on. Another project is K10 which seems to have failed to take off.

HAL is pursuing HTFE-25 engine project. If they succeed, it will power HTT-40.

My mistake. It's GTRE.
What I meant for MANIK that it can be base for bigger aircraft engines.
Anyway, there was a project for UAV engine Ghatak too whose funding was cleared by government. Any update on that @sasum ?
