First hot test of the Semi-cryogenic engine conducted at IPRC, Mahendragiri

So there was sudden spike in turbine pressure and loss in turbine speed resulted in abortion of test

First hot test of the Semi-cryogenic engine conducted at IPRC, Mahendragiri

On July 1, 2023, ISRO conducted the first hot test on an intermediate configuration of the Semi-cryogenic Engine, known as Power Head Test Article (PHTA) at ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu. The test was conducted towards developing a 2000 kN thrust semi-cryogenic engine to power the booster stages of future launch vehicles.
The objective of the test was to validate the integrated performance of the critical subsystems such as the gas generator, turbo pumps, pre-burner and control components by carrying out a hot-firing for a short-duration of 4.5 s. The ignition and generation of hot-gas within the pre-burner chamber that drives the main turbine to drive the fuel and oxidiser pumps, was focussed.
The test proceeded as predicted till 1.9 s validating the ignition and subsequent performance of PHTA. At 2.0 s, an unanticipated spike in the turbine pressure and subsequent loss of turbine-speed was observed. As a precautionary step, the test was terminated. Analysis under progress would offer further understanding before proceeding with further hot-tests for longer duration.
The semi-cryogenic engine utilizes a propellant combination of Liquid Oxygen (LOX) and Kerosene, and the power head test article forms the first hardware test of the engine development program. The test was carried out the dedicated test facility recently established at IPRC for testing semi-cryogenic engines and stages. ISRO had commenced the testing of the PHTA in May 2023 at this facility.

Teething troubles, but I'm glad they have moved into hot testing phase.

Give it a couple more years, this engine is the key to ISRO's future.

It could be caused by factors such as improper fuel mixture, a malfunctioning valve, a fuel supply disruption, or a mechanical failure within the turbine.
But most likely fuel related

the problem with SCE-200 is it's throttle range, it can achieve only 60%,but it needs atleast 40% to land

40% continuous thrust, right ??

Can't the fuel flow be controlled to generate small pulses of thrust ?, so that we can compensate for overpowered 60% minimum throttle limit ??
It might be more difficult to land/control than continuous combustion but thats what cards we are dealt with.

Exhaust profile , continuous flame, lot of factors work simulations so you just can't put a valve, if you remember the throttling of even solid boosters is done by reducing the exhaust area or the exhaust profile

40% continuous thrust, right ??
