The LPG Based Anti Hail Gun
Welcome visitors to your site, introducing you to an innovative technology built indigenously with better quality and service.
Solution
Hailstorms cause significant damage to crop production and result in substantial losses, amounting to thousands of crores, for farmers and horticulturists.
Farmers do not get the best price for their crops in the market and thus have to bear heavy financial losses every year.
Hailstorms also damage many public and private properties and can injure many living species.
Alternative hail protection systems are too expensive and require high maintenance. Traditionally people are using anti-hail nets which are too much expensive and difficult to install.
Anti-Hail Nets Installed In An Apple Orchads, Shimla to protect crops from hail damage
We, at Kripsika Innovations Pvt. Ltd., are pleased to present a proposal for introducing our advanced anti-hail gun technology to the farmers of Himachal Pradesh. This innovative solution, developed in collaboration with the esteemed Aerospace Engineering Department of IIT Bombay and funded by the Department of Science and Technology, is designed to combat hailstones that severely impact sensitive crops such as fruits and vegetables.
Sound, Shockwave & Vortex Ring-Generator for Bird Strike Prevention in Aviation
About
The Innovation
Bird strikes remain one of the most critical challenges in the aviation sector, particularly during the take-off and landing phases of aircraft operations. These incidents can result in severe engine damage, endanger passenger safety, and lead to substantial financial losses for airlines and airport operators. Bird problems aren’t limited to active runways, either; hangars housing planes are also vigilant in preventing birds from perching on, roosting in, and especially pooping on planes, as bird excrement is highly acidic and can erode a plane's exterior. Hangars generally scare off birds by placing realistic owl figurines in the space, but high-tech alternatives, like machines circulating air scented with aromas that repel birds, also exist, and are even in use at airports like Chicago-O'Hare
Bird Management at Airports
Bird strikes are one of the most common and dangerous hazards faced by airports worldwide. To protect aircraft engines and ensure safe operations during takeoff and landing, airports have historically employed various methods to deter birds from runways and surrounding areas.
Traditional Bird Control Methods
-
Firecrackers
-
Airports often use firecrackers to create loud bangs that startle and disperse birds.
-
While effective in the short term, birds quickly adapt to the noise, rendering it less effective over time.
2. Shotguns and Blank Cartridges
-
In some regions, shotguns or rifles with blank cartridges are used to generate noise that scares birds away.
-
This creates an immediate reaction but raises safety, environmental, and ethical concerns.
3. Gas Cannons
-
Stationary cannons that generate powerful sounds (up to 150 dB) at intervals, sometimes motion-activated or remote-controlled.
-
Often used in combination with other visual or sound-based deterrents to combat habituation.
Disadvantages of Traditional Methods
-
Short-term Effectiveness: Birds become habituated to repeated sounds.
-
Pollution: Firecrackers release smoke and chemical pollutants harmful to the environment.
-
Safety Risks: Handling explosives or firearms near airports can endanger staff and operations.
-
Operational Inefficiency: Requires manual deployment, increasing labour and costs.
-
Disturbance: Can disturb nearby communities due to continuous noise pollution.
Technology Overview
We, Kripsika Innovations Pvt. Ltd., in collaboration with IIT Bombay’s Aerospace Engineering Department, are pleased to propose the deployment of a Sound, Shock, and Vortex Ring Generator system to address the persistent challenge of bird strikes at airports.
Bird strikes remain a significant safety hazard for both civil and defence aviation, resulting in costly engine damage, flight delays, and potential threats to human life. Traditional preventive measures, such as firecrackers, shotguns, and sirens, have shown limited effectiveness and bring along various disadvantages, including a short range, inconsistent efficiency, and environmental disturbance.
The proposed Shockwave Bird Deterrent Gun is an advanced device designed to keep birds away from runways during aircraft landing and takeoff.
Our Proposed Technology
The Shock, Sound, and Vortex Ring Generator is an LPG-fueled device that creates a powerful combination of:
-
Strong sound waves (100–110 dB)
-
High-energy shockwave pulse
-
Visible vortex rings travelling 100–500 meters
This unique combination makes the system highly effective in dispersing bird flocks from active runways and flight paths.
Advantages over Traditional Methods
-
Non-lethal & Safe – The system causes no harm to birds or humans, even if fired directly. It only creates a deterrent effect through shock and sound.
-
Economical – Operating on LPG, it is 20 times more cost-effective compared to continuous use of firecrackers and firearms.
-
Durable Design – Built with weather-resistant materials for long-term operation in airport conditions.
-
High Effectiveness – The combination of sound waves and vortex rings reaches farther and is more efficient in breaking bird formations compared to conventional noise-based systems.
-
Movable Deployment – The system can be mounted on jeeps or movable platforms for flexible usage across different airport zones.
-
Minimal Airspace Impact – The shock and vortex effect is localised and temporary, ensuring it does not interfere with aircraft aerodynamics during takeoff and landing.
-
Dual Utility – In addition to bird control, the system can occasionally be used to neutralise small unauthorised drones (<500g) near the runway, further enhancing airport security.
The adoption of this next-generation bird strike prevention system will provide airports with a safe, sustainable, and highly effective solution to one of aviation’s most persistent challenges. We are confident that our Shock, Sound, and Vortex Ring Generator will significantly reduce bird strike incidents, safeguard aircraft engines, and ensure uninterrupted airport operations.
Proposed Implementation
-
Fixed Installations: At critical runway points and bird-attraction zones.
-
Mobile Units: Mounted on jeeps for rapid response in case of sudden bird congregation.
-
Integration with AI Monitoring: Future upgrades to include radar or camera-based bird detection for automatic operation.
Key Features
-
Shockwave Generation: Produces a sound shockwave of 100–110 dB, effective over 100m to 500m, depending on the operational requirement.
-
Fuel Efficiency: Operates on Liquefied Petroleum Gas (LPG), making it 20 times more economical than conventional bird-scare methods such as pyrotechnics or firecrackers.
-
Bird Safety: The device does not physically harm birds; it only generates sound and shockwaves that safely scare them away from sensitive areas.
-
Deployment Options:
-
Fixed installation near runways.
-
Mobile mounting on jeeps or airport vehicles for flexible coverage.
-
-
Durability: Manufactured with weather-resistant, long-lasting materials, ensuring high reliability in diverse climatic conditions.
-
Cost Efficiency: Each blast costs only ₹0.50 to ₹1.00, ensuring long-term affordability.
-
Adjustable Intensity: Sound levels and frequencies can be increased or reduced in real-time as needed.
-
Dual Action: Unlike older propane guns, this device combines both high-decibel sound and shockwaves for maximum effectiveness.
-
Environmentally Safer: Generates minimal pollutants compared to traditional methods like shotguns and firecrackers.
