ISRO shares a detailed update on its LOX-Methane engine programme, the propulsion planned for the Next Generation Launch Vehicle (NGLV) and for the future heavy-lift vehicle for India's crewed lunar landing (target 2040).

Why methane?
- Clean combustion
- Low maintenance, which helps reusability
- Can be made on Mars from CO2 + water ice, which helps future Mars missions and human settlement

LM20-TD: the demonstrator (2019–2020)
- 20-tonne thrust technology demonstrator built from existing CE-20 cryogenic engine subsystems
- Converted to LOX-CH4 by modifying the propellant flow control and engine start-up systems
- Gas generator cycle, with thrust chamber, fuel-rich GG, LOX & fuel turbopumps, igniter, and a mixture ratio control valve with electric drive
- Test sequence worked out with an in-house mathematical model
- 1 cold flow + 5 hot tests at IPRC
- Gave key data on chill-down, ignition, engine start, combustion and rotor-dynamics

LME1100: the main engine (started 2023)
- 1100 kN thrust, Gas Generator Cycle
- Designed to be industry-friendly and cost-effective
- Over 70% of components made by additive manufacturing (3D printing) with industry partners across India

Gas Generator
- 3D printed, in qualification tests at IPRC
- Sub-scale GG tests worked out the ignition sequence with a spark torch igniter and tested the 3D-printed injector elements
- First ignition test of the full-scale GG on October 9, 2026, with more tests planned

Thrust Chamber
- Sub-scale hot test campaign at IPRC
- Proved the new manufacturing methods planned for the full-scale chamber
- Settled the best injector configuration
- Showed both oxidiser-rich and fuel-rich spark torch igniters working

Turbopumps
- LOX and methane turbopumps made by Indian industry
- 3D-printed LOX pump impeller spin-tested at LPSC up to its rated speed
- Seals and bearings in qualification at LPSC and IPRC
- Cold flow tests of the integrated turbopumps ongoing at IPRC

Ignition systems
- GOX-GCH4 spark torch igniters, oxidiser-rich and fuel-rich
- Semiconductor spark plug igniter (LPSC + VSSC + IIST)
- Laser ignition, demonstrated with GOX-GH2 and GOX-GCH4

What's next
- Integrated LME1100 engine ready by mid-2027, followed by a hot test series including different thrust throttling profiles
- Design completed for a 2400 kN Full Flow Staged Combustion Cycle (FFSCC) engine, meant for a future human-rated heavy-lift launch vehicle for crewed lunar landing missions

प्रत्येकाला एक मोलाचा फुकट सल्ला...

- डाळ, तांदूळ, तेल, गहू, इतर धान्याच्या किमती काही दिवसात आकाशाला भिडतील.
-भाजीपाल्याचे, दैनंदिन वस्तू, दूधाचे दर सुद्धा झपाट्याने वाढतील. - राज्यात दुष्काळ, जगात युद्ध, इंधन महाग, रुपयाचं अवमुल्यन, शेअर बाजार धडाम.
- महागाईचं टिझर आत्ता सुरुये. पिक्चर अजून दिसायचा आहे. - परिस्थिती भयंकर होणार आहे. पैसे जपून वापरा, खर्च कमी करा, गरजुंना मदत करा.
- शक्य आणि गरज असेल तितकं साठवून ठेवा.
- नोकरदार असाल तर उधळपट्टी तातडीने थांबवा. ईएमआयवर वस्तू अजिबात घेऊ नका.
- लाएबलिटी कमी करा

▪️Joint measurement surveys for the upcoming Nagpur-Goa Shaktipeeth Expressway project fully completed in 144 villages!

▪️Fresh joint measurement surveys recently began in Sangli, Solapur and Kolhapur districts as well.

▪️Joint measurement surveys are currently underway in the remaining 265 villages.

▪️Joint measurement has already concluded in many districts of Vidharbha like Wardha and Yavatmal.

▪️The Government of Maharashtra has charted out a 16-month plan for completing the land acquisition for the ambitious Nagpur-Goa Shaktipeeth Expressway.

▪️According to this plan, the government is planning to complete the entire land physical acquisition by December 2027 and begin the actual on-ground construction work by January 2028.

▪️To truly understand the massive scale of this ambitious expressway projects, let's look at some numbers.
Around 8760 hectares of land will be required for this project across 13 districts, 40 talukas and 409 villages!

▪️Here are the district-wise lengths of Shaktipeeth Expressway as per the revised alignment:

• Wardha: 35 km
• Yavatmal: 137 km
• Nanded: 20 km
• Hingoli: 70 km
• Parbhani: 60 km
• Beed: 39 km
• Latur: 43 km
• Dharashiv: 40 km
• Solapur: 130 km
• Satara: 49 km
• Sangli: 72 km
• Kolhapur: 125 km
• Sindhudurg: 36 km
👉 Total: 856 km

▪️Yavatmal, Solapur and Kolhapur districts have the highest lengths of the expressway passing through them.

असा दिलखुलास आणि सत्य संवाद फक्त माझच नेता करू शकतो...

मुख्यमंत्री जर परप्रांतीय लोकांचा बसवला असेल तर महाराष्ट्रातील तरुण खपणारच..

असो ...

माझा नेता या महाराष्ट्रातील प्रत्येक कुटुंबाला एकट पडू देणार नाही याबाबत ठाम आहे ...
