When Abdali came, he defeated Marathas only....? What did he do in Ghallughara? Sikh soldiers did not even challenged him in Ghllughara. Sikh Raj came because Pathans, Marathas and Mughal power had vaned in Punjab. There was a vacuum and small powers.

Executive Overview Hybrid Chemical-Nuclear Mars Transport System Goal: Deliver 300 metric tons of payload to Mars orbit in approximately 7 days Concept Summary This architecture uses a two-phase hybrid propulsion system: • Phase 1 (Chemical): A scaled reusable single-stage-to-orbit (SSTO) vehicle lifts the full 300-ton payload from Earth’s surface directly to Low Earth Orbit (LEO) using methalox propulsion. • Phase 2 (Nuclear): In LEO, the payload docks with or transfers to a dedicated Nuclear Thermal Propulsion (NTP) stage that performs the high-energy interplanetary burn for a rapid 7-day transit to Mars. The system combines proven chemical heavy-lift technology with high-performance nuclear propulsion for the deep-space portion of the mission. Key Technical Features Chemical Ascent Stage (Earth to LEO) • Scaled methalox SSTO vehicle with 2,000–4,000 tons of propellant. • 3× linear-scaled Raptor-class engines (~22–25 MN thrust each). • 3× scaled helical-inducer turbopumps for high flow and cavitation resistance. • Long (3–4×) altitude-adaptive nozzle with internal vanes and secondary injection for efficient sea-level to vacuum performance. • Stainless steel tanks with internal radial-vane baffles and propellant management devices (PMDs) for excellent sloshing control during high-g maneuvers and flips. Nuclear Transfer Stage (LEO to Mars) • Nuclear Thermal Propulsion using liquid hydrogen propellant. • Specific impulse: ~900 s. • Reactor thermal power: 1.5–4 GW range. • Hydrogen tank volume: approximately 13,000–20,000 m³. • High-thrust capability for aggressive departure trajectories. Performance Projections • Payload to LEO: 300 metric tons (via scaled chemical SSTO). • Earth departure V∞: Up to 18–22 km/s (enabled by NTP efficiency). • One-way transit time to Mars: ~7 days (high-energy trajectory). • Return capability: Symmetric high-energy nuclear burn with aerocapture at Earth. • Total architecture: Reusable chemical stage reusable or semi-reusable nuclear stage. Advantages • Maximizes payload delivery using existing methalox infrastructure for the heavy-lift phase. • Achieves dramatically reduced transit times compared to traditional chemical-only missions. • Leverages high vacuum performance of the long vaned nozzle during chemical ascent and the high Isp of NTP for interplanetary travel. • Radial-vane tank design provides robust propellant stability across both phases. Challenges • Significant scaling of the chemical SSTO vehicle. • Development and flight qualification of high-power restartable nuclear thermal engines. • Large cryogenic hydrogen storage and boil-off management in LEO. • Regulatory, safety, and political considerations for nuclear propulsion in space. This hybrid approach offers a practical path to heavy-payload, high-speed Mars missions by using chemical propulsion where it excels (Earth launch) and nuclear propulsion where it provides the greatest advantage (deep-space speed and efficiency). Status: Conceptual design ready for further detailed engineering analysis, trajectory optimization, and subsystem trade studies.

While he was getting you to be his girlfriend, how many dudes did you sleep with? 3-4? That's why he freaked out and possibly not admitted by OP. She kept him as last resort while letting him keep trying. She was seeing other dudes while he was "forbidden" to even look at someone else, because the moment his interest vaned, you stepped in to prop him up just enough until you let the last few dudes run through you before "I'm ready to settle." People, "land marries land", which means high body count women and high body count men could join forces and not get upset with each other's numbers.

The video of the incident suggests he was trying to turn right, nose up, but sideslipped right, after which, the aircraft lost speed, weather-vaned into a flat left turn and descended into the trees: bit.ly/4uGKyuG.

These are not parts from any fighter jet or plane of any kind. Grok drilldown👇🏼 - First photo: A curved, dark metal panel/cover (possibly a transmission housing, oil pan, or access plate) with “S017” boldly stenciled/painted on it. It has some surface rust and damage but is otherwise a simple stamped/formed steel piece. - Second photo: Heavily corroded, riveted sheet-metal panels with remnants of gray/blue and red paint (including what looks like a white stripe). This has the look of a vehicle fender, body panel, or skid plate—thick steel that’s pitted and flaking from long-term exposure. - Third photo: A collection of mechanical parts laid out on gravel: torque converter (the spiral-vaned unit), clutch drums/plates, ring gears, planetary gear sets, and other transmission internals. These are classic automatic transmission components (common in older cars, trucks, or industrial vehicles like GM/Ford-style units). *They appear decades old (likely 20–50 years weathered).

At first we were pretty positive about the prequels. Then slowly, as enthusiasm vaned, we realized they were pretty flawed compared to the stellar original trilogy. Then we saw the sequels, and realized things could get a lot worse.

Funny thing is this is actually true Ottoman polymath named Taqi al-Din invented a rudimentary steam turbine in 1551. Known as a "steam jack," this device used a concentrated jet of steam to turn a vaned wheel, which was then mechanically linked to a spit for rotating meat

A torque converter is a very specific implementation of fluid coupling. It relies on bulk flow with vaned pump and turbine elements, usually turbulent, designed to handle high power, high slip, and large speed differences. It is optimized for vehicles. It has a stator to bias momentum transfer and achieve torque multiplication at low speeds. The geometry is fixed and the operating regime is well understood and heavily engineered. The NYU and NYU Shanghai device uses viscous shear between closely spaced rotating elements. The dominant mechanism is controlled momentum diffusion in laminar or weakly transitional flow, not jet-like flow off vanes. Torque scales smoothly with viscosity, gap spacing, and relative speed. There is no stator, no torque multiplication in the automotive sense, and no expectation of high efficiency at large power levels. It behaves more like a continuously tunable viscous clutch that can be arranged to mimic a gear ratio over a narrow operating window.
