Rotating Detonation Engine (RDE)

ЁЯФ╣ Why in News & Recent Development

On August 18, 2026, India-based defence start-up D-Propulse announced the successful demonstration of a Rotating Detonation Engine (RDE) at a Defence Research & Development Organisation (DRDO) facility in Hyderabad. This development marks a significant step forward in indigenous advanced propulsion technology, which could fundamentally transform future high-speed missile and space launch systems.

ЁЯФ╣ Mechanism of Detonation vs Deflagration

Conventional rocket and gas turbine engines rely on deflagration, which is a subsonic, steady burn of fuel using a flame. In contrast, an RDE utilizes detonation, where the fuel-oxidizer mixture combusts via rapid supersonic explosions that continuously rotate inside a ring-shaped chamber. This supersonic shockwave compresses and ignites the fuel, releasing energy far more rapidly and efficiently than conventional combustion.

ЁЯФ╣ Operational Benefits and Design Advantages

Because the detonation process occurs at higher pressures, RDEs produce significantly more thrust for the same quantity of fuel. This dramatic volume saving allows for increased payload capacity or extended fuel volume, giving missiles and space vehicles a longer operating range and higher velocities. Additionally, RDEs are mechanically simple, featuring no moving parts, which reduces manufacturing complexity and lowers production costs compared to complex gas turbines.

Supreme Court Directives on Electoral Black Money

ЁЯФ╣ Why in News & Recent Development

On August 18, 2026, the Supreme Court of India issued a landmark order holding that preventing the influence of black money in elections is a constitutional duty of the Election Commission of India (ECI). The Court laid down strict, time-bound instructions to monitor, seize, and prosecute illegal cash flows during elections.

ЁЯФ╣ Major Directives Issued by the Apex Court

The Supreme Court mandated that any cash or asset seized during elections must be reported to the competent court or District Magistrate within 24 hours. All election-related FIRs must have their investigations completed within one year, with status reports submitted quarterly to the ECI. Any cash seizures exceeding Rs. 10 lakh by Static Surveillance Teams must be forwarded immediately to the Income Tax department. Crucially, the withdrawal of any criminal case against candidates during an election cycle now requires the approval of the respective state High Court.

ЁЯФ╣ Constitutional and Jurisprudential Grounding

The Court emphasized that money-grubbing in elections subverts Article 326 (Universal Adult Suffrage) by commodifying votes. It noted that financial inequality between candidates destroys the level playing field guaranteed under Article 14 (Right to Equality). The judgment cited the NOTA Judgment (PUCL v. Union of India, 2013), Indira Nehru Gandhi v. Raj Narain (1975) (which declared free and fair elections a part of the Basic Structure), and the Electoral Bonds Case (ADR v. Union of India, 2024), which struck down anonymous funding under Article 19(1)(a).

ЁЯФ╣ Statutory Context and Historic Committee Recommendations

Under Section 123(1) of the Representation of the People Act (RPA), 1951, bribery is treated as a corrupt practice. However, candidates exploit loopholes like Section 77 (which caps candidate expenses but not political party expenses) and Section 29C (exempting donations under Rs. 20,000 from disclosure). The judgment builds upon recommendations from the Dinesh Goswami Committee (1990) (state funding in kind), the Vohra Committee (1993) (criminal-political nexus), and the Law CommissionтАЩs 255th Report (2015) on electoral reforms.

NITI Aayog Report on Professional Services Regulatory Regime

ЁЯФ╣ Why in News & Recent Development

In August 2026, NITI Aayog released a detailed report titled 'India's Services Sector: Insights on Regulatory Regime in Professional Services.' The report highlights the regulatory bottlenecks that restrict India's high-value professional services, such as accounting, legal, and engineering, from expanding globally.

ЁЯФ╣ Economic Weight and Comparative Advantage

The services sector accounted for approximately 55% of India's GDP and GVA in FY24, contributing 30% of total national employment. Professional and consulting services accounted for ~20% of services exports. IndiaтАЩs Revealed Comparative Advantage (RCA) in this segment rose to 3.0 in 2024, demonstrating strong global competitiveness. However, the OECD's Services Trade Restrictiveness Index (STRI) places India's legal, accounting, and architectural services among the most restrictive worldwide.

ЁЯФ╣ Key Sectoral Challenges and Restrictions

For legal services, the Advocates Act, 1961 does not recognize Corporate/Multi-Disciplinary Practices (MDPs), and India has no Mutual Recognition Agreements (MRAs) with international bodies. Accounting faces dual oversight from the ICAI and the National Financial Reporting Authority (NFRA). Civil engineering lacks a unified statutory regulator, as the Engineers Bill remains pending. Under the General Agreement on Trade in Services (GATS), India has made no commitments in legal and architectural services, and has capped Mode 3 (Commercial Presence) foreign equity at 51% in engineering.

ЁЯФ╣ NITI AayogтАЩs Actionable Recommendations

NITI Aayog recommends a four-pronged approach: instituting a mandatory Continuous Professional Development (CPD) hour system, adopting global regulatory consultation models like Malaysia's UPC portal, utilizing IndiaтАЩs 1,700 Global Capability Centres (GCCs) to shift to knowledge-intensive exports, and preparing for AI/automation in consulting and green carbon accounting.
