Radial turbines are used for small engines and are cheaper and easier to manufacture but have lower efficiencies. Turbine blades can be cooled internally using convection or impingement, or externally using film or effusion cooling to distribute coolant over the blade surface. Sealing systems in gas turbines use different types of seals like labyrinth, ring, hydraulic, carbon, and brush seals to prevent oil leakage and control cooling airflows, with ring seals commonly used except in hot areas and specialized seals to prevent hot gas ingestion into turbine disc cavities.
Steam turbines convert the heat and pressure energy of steam into rotational mechanical energy. They use either impulse or reaction principles. Impulse turbines use nozzles to convert steam pressure into velocity before it strikes moving blades, while reaction turbines allow continuous expansion of steam through fixed and moving blades.

The Evolution and Impact of OTT Platforms: A Deep Dive into the Future of Ent...ABHILASH DUTTA
This presentation provides a thorough examination of Over-the-Top (OTT) platforms, focusing on their development and substantial influence on the entertainment industry, with a particular emphasis on the Indian market.We begin with an introduction to OTT platforms, defining them as streaming services that deliver content directly over the internet, bypassing traditional broadcast channels. These platforms offer a variety of content, including movies, TV shows, and original productions, allowing users to access content on-demand across multiple devices.The historical context covers the early days of streaming, starting with Netflix's inception in 1997 as a DVD rental service and its transition to streaming in 2007. The presentation also highlights India's television journey, from the launch of Doordarshan in 1959 to the introduction of Direct-to-Home (DTH) satellite television in 2000, which expanded viewing choices and set the stage for the rise of OTT platforms like Big Flix, Ditto TV, Sony LIV, Hotstar, and Netflix. The business models of OTT platforms are explored in detail. Subscription Video on Demand (SVOD) models, exemplified by Netflix and Amazon Prime Video, offer unlimited content access for a monthly fee. Transactional Video on Demand (TVOD) models, like iTunes and Sky Box Office, allow users to pay for individual pieces of content. Advertising-Based Video on Demand (AVOD) models, such as YouTube and Facebook Watch, provide free content supported by advertisements. Hybrid models combine elements of SVOD and AVOD, offering flexibility to cater to diverse audience preferences.
Content acquisition strategies are also discussed, highlighting the dual approach of purchasing broadcasting rights for existing films and TV shows and investing in original content production. This section underscores the importance of a robust content library in attracting and retaining subscribers.The presentation addresses the challenges faced by OTT platforms, including the unpredictability of content acquisition and audience preferences. It emphasizes the difficulty of balancing content investment with returns in a competitive market, the high costs associated with marketing, and the need for continuous innovation and adaptation to stay relevant.
The impact of OTT platforms on the Bollywood film industry is significant. The competition for viewers has led to a decrease in cinema ticket sales, affecting the revenue of Bollywood films that traditionally rely on theatrical releases. Additionally, OTT platforms now pay less for film rights due to the uncertain success of films in cinemas.
Looking ahead, the future of OTT in India appears promising. The market is expected to grow by 20% annually, reaching a value of ₹1200 billion by the end of the decade. The increasing availability of affordable smartphones and internet access will drive this growth, making OTT platforms a primary source of entertainment for many viewers.

Turbofan Turboshaft APUs
Turboprop Turbojet
Turbofan engines: Boeing predicts growth in the air travel market by about 5% per year over the next
two decades owing to the growing global economy. At the same time, airlines profits are also rising
due to the growing demand for air travelling. According to the forecast of the International Air
Transport Association (IATA), consolidated net returns of the market participants in 2015 will reach $
29.3 billion., While in 2014 it was $ 16.4 billion., In 2012 - $ 7.4 billion. The industry’s trends mentioned
above will allow airlines to place large orders for new aircrafts, which causes the demand for engines.
Turboshaft engines : Demand for turboshaft engines will grow stably in the medium term, owing to the
demand for light commercial helicopters (therefore driving engine production), which are
increasingly being used for utility tasks. Military’s segment demand will fall.
APU: Demand for auxiliary power units (APUs) will steadily increase due to the fact that such systems
are used in many types of aircraft. However, despite the fact that the APU occupies 19.5% of the
produced gas turbine engines, because of their low cost, it is a tiny fraction of the value of the
aviation gas turbine market overall.
Turboprop engines: In the period from 2016 to 2029 the volume of production of turboprop engines will
be reduced by the fact that, in view amalgamation and strengthening of the major airlines operating,
both on local routes, the opportunity for local air carriers will be reduced. This will cause the decline in
demand for regional aircrafts (Cessna, Beechcraft King Air, etc.), and as a consequence, decrease in
demand for turpoprop engines.
Turbojet Engines : Aircraft manufacturers abandoned turbojet engines for most applications long ago
due to their lower efficiency compared with turbofan engines, but they remain useful for applications
requiring a high power-to-weight ratio specifically for missile / air targets and to a lesser extent in UAVs
since turbojets have a high power-to-weight ratio, but low fuel efficiency, that makes turbojets
unsuitable for many UAVs tasks.

The world market for industrial gas turbines is
quite complex and occupies a large portion
of the production capacity of several very
large firms in Europe, Asia, and the United
States. This activity is rapidly becoming ever
more important, as gas and steam turbines
(often in combined cycle applications) are
increasingly sought as prime movers for
application within the world's power and
energy industries.
Faced with potential global warming as well
as pollution problems, the energy industry is
phasing out hundreds of coal burning plants in
favor of clean burning gas turbines powered
by natural gas or other fuels that provide far
less noxious emissions. At the same time, many
countries, having experienced or witnessed
harrowing near disaster nuclear scenarios,
have made the decision to phase out nuclear
facilities in favor of much safer and
controllable gas turbines.
Therefore, the trend of increasing demand for
gas-turbine power plant can be marked.
